College students were randomly sorted into one of two groups. Members of each group performed a series of mental tasks while music was playing in the background. One group listened to pop music and the other to country music. It is hypothesized that music will effect the number of tasks completed. What can be concluded with an α of 0.10? The results are below:

pop country
1 = 39.31

1 =

5.43
n1 = 10
2 = 44.15

2 =

3.2
n2 = 12

b)
Condition 1: (choose one)
1) pop music 2) school 3) country music 4) mental task 5)music
Condition 2:
1) pop music 2) school 3) country music 4) mental task 5)music

c) Obtain/compute the appropriate values to make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =____________ ; test statistic = ________________
Decision:  ---Select--- Reject H0 Fail to reject H0

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[ ________, ___________ ]

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d = _____________ ;  (choose one) 1) na 2) trivial effect 3) small effect 4) medium effect 5) large effect
r2 = ____________ ;  (choose one) 1) na 2) trivial effect 3) small effect 4) medium effect 5) large effect

f) Make an interpretation based on the results.

1) Students that listened to pop music significantly completed more tasks.

2) Students that listened to country music significantly completed more tasks.    

3) Music had no significant effect on the number of tasks completed.

1) Identify the items to be included in the capital budgeting analysis.

2) Ascribe values to the items identified part 1. These values should capture the effects of inflation on the variable cost per unit and the prices of product. Assume that the project will end in five years and the exchange rate is expected to depreciate 3 % each year for the next 3 years, appreciate by 2% in year 4 and 4% in year in year 5.

Create a Python file named num_sum.py that contains:

  • The definition of two functions:
    • volume - accepts three parameters and returns the product of them, but displays nothing
    • sum_of_nums - accepts 1 or more numbers and returns their sum, but displays nothing
  • A print function call that includes a call to volume, passing 2, 3, and 4
  • A print function call that includes a call to sum_of_nums, passing 1, 2, 3, 4, and 5

Consider a population proportion p = 0.88.

a-1. Calculate the expected value and the standard error of P−P− with n = 30. (Round "expected value" to 2 decimal places and "standard deviation" to 4 decimal places.)

b-1. Calculate the expected value and the standard error of P−P− with n = 60. (Round "expected value" to 2 decimal places and "standard deviation" to 4 decimal places.)

A marketing organization wishes to study the effects of four sales methods on weekly sales of a product. The organization employs a randomized block design in which three salesman use each sales method. The results obtained are given in the following table, along with the Excel output of a randomized block ANOVA of these data.

Set α = .05. Can we conclude that the different sales methods have different effects on mean weekly sales? F = 36.23, p-value = .000; H0: there is a in sales methods. (b) Test the null hypothesis H0 that no differences exist between the effects of the salesmen (blocks) on mean weekly sales. Set α = .05. Can we conclude that the different salesmen have different effects on mean weekly sales? F = 12.87, p-value = .007; H0: salesman have an effect on sales. (c) Use Tukey simultaneous 95 percent confidence intervals to make pairwise comparisons of the sales method effects on mean weekly sales. Which sales method(s) maximize mean weekly sales?
