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 = 5.43n1 = 10 |
2 = 44.15
2 = 3.2n2 = 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.

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. Salesman, j Sales Method, i A B C 1 32 29 30 2 32 30 28 3 28 25 23 4 25 24 23 ANOVA: Two-Factor without Replication SUMMARY Count Sum Average Variance Method 1 3 91 30.3333 2.3333 Method 2 3 90 30 4 Method 3 3 76 25.3333 6.3333 Method 4 3 72 24 1 Salesman A 4 117 29.25 11.5833 Salesman B 4 108 27 8.6667 Salesman C 4 104 26 12.6667 ANOVA Source of Variation SS df MS F P-Value F crit Treatments 93.5833 3 31.1944 36.2258 0.0003 4.7571 Blocks 22.1667 2 11.0833 12.8710 0.0068 5.1433 Error 5.1667 6 0.8611 Total 120.9167 11 (a) Test the null hypothesis H0 that no differences exist between the effects of the sales methods (treatments) on mean weekly sales. 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? (Round your answers to 2 decimal places. Negative amounts should be indicated by a minus sign.)
