1. Read the iris data set into a data frame.

2. Print the first few lines of the iris dataset.

3. Output all the entries with Sepal Length > 5.

4. Plot a box plot of Petal Length with a color of your choice.

5. Plot a histogram of Sepal Width.

6. Plot a scatter plot showing the relationship between Petal Length and Petal Width.

7. Find the mean of Sepal Length by species. Hint: You could use the tapply function. Other methods are also acceptable.

8. Use the subset function to extract only rows where the species is "versicolor."

9. Install the dplyr package and load it on your console.

10. Use a function in the dplyr package to show only rows with Sepal Length <6 belonging to species "virginica."

Submit all the code and subsequent output as a word file

You have been asked to conduct a study related to consumer loyalty toward three different retail formats (i.e., department stores, specialty stores, and off-price retailers). After gathering background information, you decide to focus your study on three research streams; retail service quality, consumer satisfaction, and consumer loyalty. The literature suggests that there are five dimensions of retail service quality; physical aspect, reliability, personal interaction, problem solving, and policy. According to the literature, consumer satisfaction is a unidimensional construct and consumer loyalty consists of two dimensions; word-of-mouth and behavioral intention. You want to learn whether or not influencing factors of consumer loyalty are different between these three types of retailers.

J Company produces copy paper. The company has established the following direct materials and direct labor standards for one case of copy paper:

Paper pulp (3 lbs. @ $0.40) $ 1.20

Labor (2 hrs. @ $12) 24.00

Total prime cost $25.20

During the first quarter of the year, J Company produced 45,000 cases of copy paper. The company purchased and used 135,700 pounds of paper pulp at $0.38 per pound. Actual direct labor used was 91,000 hours at $12.10 per hour.

Required:

1. Calculate the direct materials price and usage variances.

2. Calculate the direct labor rate and efficiency variances.

3. Prepare the journal entries for the direct materials and direct labor variances.

Note: please provide your explanations on spreadsheet or Word as written solutions are difficult to read

1. View the following 3 TED Talks (video presentations). As you watch the videos, take notes of any relevant information. Inside the mind of a master procrastinator | Tim Urban The habits of highly boring people | Chris Sauve The Art of Letting Go | The Minimalists 2. Decide which of the 3 TED Talks best responds to this question; How can identifying your opportunity costs, help you make better choices? 3. Produce a no more than 200 word Post in which you explain your position. Your post must contain at least the following elements: It must state the title and the author of the chosen TED talk. It must state the reason why believe that TED talk best answers the question. It must explicitly explain the relationship, connection, or link between the ideas provided in the TED Talk and the concept of Opportunity Cost.

Denise is conducting a study related to consumer loyalty toward three different retail formats (i.e., department stores, specialty stores, and off-price retailers). After gathering background information, she decides to focus the study on three research streams; retail service quality, consumer satisfaction, and consumer loyalty. Denise is interested in identifying factors (i.e., retail service quality) that may contribute to consumer satisfaction and consumer loyalty toward these retailers. According to the literature, consumer satisfaction is a uni-dimensional construct and consumer loyalty consists of two dimensions; word-of-mouth and behavioral intention.

Select a free ebook on gutenberg . org and download the plain text file (utf8). the ebook is (The Devil's Dictionary by Ambrose Bierce)

Write a program that does the following:

• Read in your ebook (any book, any language)
• Break the book into words (look at .split() for strings)
• Make a dictionary of all words and how often they occur: for instance if the word'the'happened 2000 time and the word'a' happened 1940 times word_dict= {'the' : 2000, 'a' :1940}
• Print the dictionary of word frequencies to a file (freqs.txt) with the most frequent at the top and least frequent at the bottom
• No need to submit the book, I will run it on my own files.

Turn in a .py or Google Colab URL

Dictionaries are not easily sortable since they are not ordered like a list. To sort for this assignment use the following template.

import operator

sorted_dict = sorted(my_dict.items(),key=operator.itemgetter(1))

I am making pie chart about my personality, but can i get an example of pie chart.

Here is example of statement that i have to fill in the blank.

-  

First identify affiliations and aspects of your self identity.

Using Excel, smartart in Word or Powerpoint, drawing in Paint or by hand, create a pie chart that represents your positionality. See mine attached as an example.

Next, fill in the blanks to the following: Because I am ______________ (major aspect in your piechart), I have a tendency to ____________ in relationships with other people who are __________. Because I am _______ other people who are ______ have a tendency to ____ in their interactions with me. Lastly, explain why you choose each and its size relative to other aspects.

Remember to write at least 100 words in your post for full credit.

""The most crucial detail is that thinking promotes social cohesion and consciousness. people acquire new skills and creative ideas by thinking about solutions to everyday problems. The second important concept emphasized is the power of knowledge. This concept equips people with more details and creativity that exceeds our imagination. Decision making is another crucial aspect that the videos teach. It enables people to choose what is right for them and reject things that may have negative consequences. , people can enhance their knowledge by reading books, watching movies, or listening to people’s narratives. However, they should understand that not all information is helpful. Therefore, they should be able to save the information they obtain from various sources to apply only useful and credible details.""

Building on your initial user interface (UI) design mock-up of the organization’s program UI, the interface now needs to present more information to the user. Complete the following for this assignment: The interface should present information visually with icons or graphics and text regarding critical issues related to the system, such as the following: New orders Change in employee status Updated pictures New products or services offered Describe techniques for developing prototypes of user interfaces. You must add at least 5 critical issue UI design items to your interface. Remember to ensure that these are easily understood by users. Submit a screenshot in Word or another functional application. Describe the items that you added to your interface design. Be specific with your descriptions, and identify the particular design features along with an explanation of why they are added in the way that they were .

1. Create a strongly typed enumerator for the days of the week, and put it in a header file enum.h

2. Create a test program with a switch statement that has a function that prints the day word based on numeric input from the user.  

3. Utilize the local predefined variable __func__ to display the name of the current function.

Student Learning Outcomes:

• Create and utilize strongly typed enumerators

• Correctly implement scope resolution for strongly typed enumerators

• Cast variable types for proper comparisons

• Display the current function’s name

STYLE NOTE: enumerators are constant, so many people think that the entire enumerator value (e.g. sunday) should be in all caps. Others follow the rule that since the variable type is created by the programmer, it should start with an uppercase letter. You may choose either one, but be consistent. I happen to use the first as it gives a clear visual indicator that it is a special variable.
