Ahmad Wazir is 34 years old, married with a three-year-old child and another on the way. He lives in a town of about 100,000 people outside Kuala Lumpur, Malaysia. After graduating with a BBA in marketing and later with an MBA in Islamic Finance, he joined one of the biggest Takaful operators, Takaful Ehsan (TE) where he built a sizeable business marketing in general and family Takaful products. But with changes in the organization and having no control over client services made him realize that his prospects for growth at TE is limited. With some savings accumulated over the years to carry him through, Wazir left his position as a senior marketing manager to become an independent Takaful advisor. Instead of targeting everyone, Wazir realized that he needed to focus on specific client segments. Hence, he decided to put his limited resources behind the most viable prospects. Many of his clients acquired during his former job had been close families in his town. Several of them had been regulars at the local mosque as well as members of the community and sports club. Wazir is of the view that one of the best approaches to screen the prospects is to conduct a geo-demographic segmentation of his own as part of the targeting and segmenting process. i) What is geo-demographic segmentation and how is it different from psychographic segmentation? ii) In conducting the geo-demographic segmentation, what are among the actions that Wazir may take in order to ensure that the prospects will fit into his target segment? iii) Why do you think that Wazir has chosen this approach?

On the last page of this file you will find the Excel output for a multiple linear regression model. The model was built in an attempt to better understand why students at area high schools perform differently on the state high school mathematics test. The average test score for a class of students is what we are trying to predict. In our attempt to understand why these test scores differ, we use 3 independent variables: a rating (0-100) for the quality of the math degree obtained by the instructor, the age of the instructor, and the salary (in thousands) of the instructor.

1. Estimate the average math score for a class of students whose instructor is 52 years old, earns $48,000, and got her degree in a math program rated 72.
2. What percentage of the variations in math scores can be explained by this model?
3. Conduct a test to determine if the model, taken as a whole, provided us with any significant explanation of the differences in math scores. That is, should the model be retained for further analysis?
4. Which of the independent variables appear to be significant to the model? Which appear to be insignificant? What leads you to these conclusions?

An apple orchard farmer wants to know the true population proportion of all apples harvested at their farm which have the less valuable condition of being blemished, or in other words, are cider apples.

This true population proportion is a parameter value represented by the symbol p. As a population parameter, this value can never be known with certainty. It can however, be estimated with varying levels of confidence.

To estimate this parameter p, the farmer draws a simple random sample (SRS) of 524 apples from the orchard. Within this sample, the farmer finds that exactly 47 of the apples are cider apples.

The farmer then computes a 96%-level confidence interval estimate for the parameter p.

In percentage form, and rounded to four digits past the decimal point: What is the approximate value of the Upper Limit of this confidence interval?

Include a percentage symbol at the end of your numerical answer (with no spaces).

In percentage form, and rounded to four digits past the decimal point: What is the approximate value of the Margin of Error for this confidence interval?

Include a percentage symbol at the end of your numerical answer (with no spaces).

Suppose the farmer now wishes that they had instead built a confidence interval with a 99% confidence level, and a margin of error no greater than 2%.

To achieve these new specifications: The farmer intends to draw another SRS of apples in the future, and build another confidence interval.

What minimum sample size of apples will the farmer have to draw, in order to achieve these new confidence interval specifications?

(Note: Your answer should be a whole number here.)

Data exploration through visualization is important because statistics alone might not tell the entire story. This is best shown by the French statistician Francis Anscombe in 1973 when he presented four sets of data. This data is shown here and show the code:

Using R programming studio, calculate the mean, variance, correlation, and linear regression for each data set (No data partition). Using base R or ggplot2, create a visual representation of this data. What does this visualization show? (show the code for each data set)

Using R studio programming, how do you evaluate and compare the developed linear regression models? Are there any issues with the models built?

Is there any way to improve the linear regression models for Data I, II, and III?

Businesses both large and small are flocking to social media platforms to engage consumers in conversations and also to drive sales through deals and coupons. Small businesses have found that social media and the Internet help them to level the playing field. They can foster closer relationships with clients and identify potential customers. Flirty Cupcakes owner Tiffany Kurtz says that Facebook and Twitter greatly helped her with product innovation, market expansion, and customer service. Many other entrepreneurs are using social media to launch and expand their businesses.

Read the article, "9 Businesses that Social Media Built (Links to an external site.)."

Using the Internet, search for small businesses that have used social media to start a business or expand their market share. Select four businesses to study. Analyze their use of social media. What do they have in common? When these companies were first launched, most of them probably needed to borrow money to get started. How might these companies have described the social media potential in writing a proposal seeking funding? In which of the proposal components would this information be best placed? In an e-mail or memo to your instructor, describe briefly the four companies you selected. Then, for one company write a portion of the proposal in which the entrepreneur explains how he or she plans to use social media to promote the business. How much time do you think the entrepreneur would need to devote to social media weekly? What platforms would be most useful?

. Gradualism is an important assumption of evolutionary theory.

A. A complex structure like the eye would be unlikely to emerge from a single large-scale mutation. How does gradualism help evolutionists address the evolution of complex adaptations, such as the eye?

B. How do ring species support a gradualist model of speciation? Explain.

2. Use the comparative method to answer the following questions about selection and adaptation, discussed Chapter 8.

A. What are convergent evolution and divergent evolution?

B. Why would selection ever delete a trait after having built it? Explain how cave-dwelling species lost the eyes that had evolved in their ancestors.

C. Why are disabling mutations in an olfactory receptor gene more likely to be “tolerated” by selection in a species with full trichromatic vision than in species without it?

D. Do you see parallels between increased loss of olfactory genes in species with trichromatic vision and the evolution of eyelessness in cave-dwelling species? Explain.

3. Altruistic traits, by definition, harm the individual manifesting the trait and help others.

A. What does Hamilton’s Rule say about the conditions under which kin selection should favor altruism?

B. In the woodpecker nest-helper example from class, explain how it can be in the evolutionary interests of a young bird to help their mother or sister breed when there are not enough nest holes to breed on their own.

C. Even when there are nest holes available, young birds sometimes help their mothers breed instead. How do “Selfish Genes” explain the evolution of behavior that is not in the interests of the individual (not facultative altruism).

D. In the case of reciprocal altruism, explain how reciprocity can maintain altruism even without close genetic relatedness.

Students will use advanced looping methods including replicate(), lapply(), sapply(), and apply(), and access datasets provided with R packages in an R script.

1. The function call, rnorm(1), generates a normal random number. Use replicate() to generate 10 normal random numbers and assign them to a vector called nums.
   
2. The R statement, data(iris), loads the built-in R data set iris. This dataset has 150 rows and 5 columns. The 5 column names are "Sepal.Length","Sepal.Width","Petal.Length","Petal.Width" and "Species".
   1. Write R code(s) to return a list of 4 items that correspond to the averages of the first 4 columns in iris. The contents of the list should be as follows:
      
      $Sepal.Length
      [1] 5.843333
      
      $Sepal.Width
      [1] 3.057333
      
      $Petal.Length
      [1] 3.758
      
      $Petal.Width
      [1] 1.199333
      
3. With the iris dataset still loaded,
   1. write R code(s) to return a vector of 4 items that correspond to the averages of the first 4 columns in iris. The contents of the vector should be as follows:

4. The following R code converts the contents of the first 4 columns in iris to a matrix called data.
   data=as.matrix(iris[,1:4])
   1. Write R code(s) to use apply() to return a vector that contains the max values of the 4 columns. The contents of the vector should be as follows [Hint, use max()]:

5. Write R code(s) to read the contents of the provided file COS-206-ShoppingCart.html into a variable called cart and then show the first 5 lines of cart.

JavaScript - Create a class using "names" as the identifier.

Create a constructor. The constructor must have elements as follow:

first ( value passed will be String )
last ( value passed will be String )
age ( value passed will be Numeric )

The constructor will assign the values for the three elements and should use the "this" keyword

Create a function, using "printObject" as the identifier

printObject:

This function will have three input parameters:

allNames , sortType, message

Will sort the array of objects (allNames) using sortType as the key to how the arrays objects will be sorted.

These sort functions, are higher order functions, one required for each sort option except none. A higher order function type is calling a function with an argument that is a function. In this assignment, one would be using the builtin sort for arrays, allNames.sort( your function here ); This function will override the default sort order, built into array.sort()

The sort options are first , last , age, none.

Will print the message to the console

Will use a loop to print out the array by index ascending and display the values located in the elements: first last age, for each index accessed

Create a function main, no input parameters

main:

Create the empty array using the identifier "allNames"

Using the push() method, load 4 new objects of names to the array allNames, populating the fields first , last , age ( data is of your choosing, for example: allNames.push( new names("Cammo", "Hammer", 39));

Call printObject, passing the array , sort method as a string ( options are first, last, age, none )

Last line of the script, would be the call to the main

Note: It is required to use the ES6 style of keywords => instead of the older function and for variables use the keyword let, not var, class and within the constructor, not function.

Problem Statement:  An urban circumferential freeway is to be designed on the basis of the following information: design year average annual daily traffic, AADT = 75,000 veh/day; the estimate of the percent of traffic occurring during the peak-hour is 9%; the percent of peak-hour traffic in the heavier direction is estimated to be 55%. The traffic mixture is expected to be similar to the current mixture of 7% trucks, 3% buses and no recreational vehicles. The PHF is estimated to be 0.9. The base free-flow speed is 70 mph. If the freeway is to be built on rolling terrain with no lateral obstructions and 12-ft lanes, determine the number of lanes needed to provide a minimum LOS of B.
