To determine the effect of various cooling devices during exercise, a researcher assigns 10 people to each of the following four groups: No Cooling Device, Only Head Cooling Device, Only Vest Cooling Device, Both Head and Vest Cooling Device. The researcher takes the body temperature of each individual after exercise and runs an ANOVA to test the null hypothesis that .

Here is the R input:

> NoCool=c(102,104,101,102,103,101,99,102,100,100)> HeadCool=c(102,102,100,101,103,101,99,101,101,100)
> VestCool=c(101,102,100,100,102,100,99,101,100,100)> HeadVestCool=c(100,99,99,100,100,99,98,100,99,99)
> Device = c(rep("None",10),rep("Head Only",10),rep("Vest Only",10),rep("Head and Vest",10))
> Temperature=c(NoCool,HeadCool,VestCool,HeadVestCool)> Temp = data.frame(Device,Temperature)
> Temp.mod=aov(Temperature~Device,data=Temp)
> anova(Temp.mod)

Here is the output:

The researcher concludes that at least one of the means is different and, as a result, runs a Tukey Test.

Here is the R input:

> TukeyHSD(Temp.mod)

Here is the output:

Question:  Which means should the researcher conclude to be different from each other at the significance level of 0.05?

AZRB is a road bridge construction company. The company plan to build a major road bridge for its new project. Table shows the process sequence and other related data for the major road bridge development.

Table :Activities to construct the bridge, estimated time and crashing cost.

1. Develop a network diagram for the above project. Determine the critical path and minimum project completion time.
2. Calculate the probability that the project can be completed in between 250 and 270 days.                                                                                                                        
3. If the project has to be shortened by five (5) days, determine which activity needs to be crashed and the additional cost involved. Cost per day as well as crash cost per day were based on expected time.

Write a program that uses an array of nested structs to store the addresses for your store’s customers.  Each customer has a name and two addresses: home address and business address.  Each address has a street, city, state, and zip code. Requirements: 1. Data structure a. Define an Address struct with street, city, state and zip fields b. Define a Customer struct with lastNm and firstNm fields, plus homeAddr and busAddr fields of type Address c. Declare an array of type Customer 2. Use a menu‐driven program with the following selections: a. Enter new customer b. Display all customers c. Display a particular customer d. Exit the program 3. Define the following 5 functions a. int displayMenu(); Outputs the menu selections Inputs the users selection Validates that the user has entered a valid selection b. Customer getCustomer(); Asks the user to input the customer’s first name, last name and the two addresses and stores in a single Customer struct c. void showCustomer(Customer); Outputs the information for a single Customer struct d. Address getAddress(); Asks the user to enter each component of the address (street, city, state and zip) and stores it in a single address struct. Note that street will contain embedded blanks, so you will need to use getline. Since you are mixing cin and getline, you will need to use cin.ignore to skip over the last endline character in the input prior to using getline. e. void findCust(Customer[], int); Asks the user to enter a customer’s first and last names Searches the array of Customers for a match If there is a match, prints out all information for the particular customer If not match, prints an error message.

For the last 50 weeks, the demand for a product was observed to be as given in the table below. For example, 250 units were demanded for 10 weeks in the span of 50 weeks (not necessarily in one single stretch!). The unit price of the product $500 and normally sells for $750, If the product is not sold during that week, it can be sold at a reduced price of $300 per unit. If it is out of stock, the lost goodwill amounts $150/unit.  

1. Calculate the probabilities for the various demands and find also the cumulative probabilities.
2. What is the appropriate value of ordering quantity? Please explain the steps.
3. If the unit selling price was increased to $900, how would your answer in part ‘b’ change?

Lester Hollar is vice president for human resources for a large manufacturing company. In recent years, he has noticed an increase in absenteeism that he thinks is related to the general health of the employees. Years ago, in an attempt to improve the situation, he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of eight participants and found the number of days each was absent in the six months before the exercise program began and in the last six months. Below are the results. Use a 0.05 significance level and determine if it is reasonable to conclude that the number of absences has decline? Use this information to solve the following questions.

A. What is the null hypothesis statement for this problem?

B. What is the alternative hypothesis statement for this problem?

C. What is alpha for this analysis?

D. What is the most appropriate test for this problem? (choose one of the following)

a. t-Test: Paired Two Sample for Means

b. t-Test: Two-Sampled Assuming Equal Variances

c. t-Test: Two-Sample Assuming Unequal Variances

d. z-Test: Two Sample for Means

E. What is the value of the test statistic for the most appropriate analysis?

F. What is the lower bound value of the critical statistic? If one does not exist (i.e. is not applicable for this type analysis), document N/A as your response.

G. What is the upper bound value of the critical statistic? If one does not exist (i.e. is not applicable for this type analysis), document N/A as your response.

H. Is it reasonable to conclude that the number of absences has decline? (choose one of the following)
