Test—CI connection In exercise 1, explain how the result of the 99% confidence interval in part b corresponds to the result of the decision using significance level 0.01 in part c.

Exercise 1

Time spent on Internet In 2006, the General Social Survey asked about the number of hours a week spent on the World Wide Web (variable denoted WWWTIME). Some results are as follows:

Group	N	Mean	StDev	SE Mean
Male	1196	6.2	9.9	0.285
Female	1569	4.9	8.6	0.216
Difference = mu(Male) − mu(Female)
Estimate for difference: 1.3
99% CI for difference: (0.4. 2.2)
T-Test of difference = 0 (vs not =):
T-value = 3.62 P-value = 0.000

a. Identify the response variable and explanatory variable. Indicate whether each variable is quantitative or categorical.

b. Report and interpret the 99% confidence interval shown for the difference between the population means for males and females.

c. Report and interpret the steps of the significance test comparing the two population means. Make a decision, using significance level 0.01.

Bobbie’s Hair Care is a natural monopoly. Table shows the demand schedule (the first two columns) and Bobbie’s marginal cost schedule (the middle and third columns). Bobbie has done a survey and discovered that she has four types of customers each hour: one woman who is willing to pay $18, one senior who is willing to pay $16, one student who is willing to pay $14, and one boy who is willing to pay $12. Suppose that Bobbie’s fixed costs are $20 an hour and Bobbie’s price discriminates.

Price (dollars per haircut)	Quantity (haircuts per hour)	Marginal cost (dollars per hour)
20	0	—
18	1	1
16	2	4
14	3	8
12	4	12
10	5	18

Who benefits from Bobbie’s price discrimination? Is the quantity of haircuts efficient?

State budgets. States that rely on sales tax for revenue to fund education, public safety, and other programs often end up with budget surpluses during economic growth periods (when people spend more

on consumer goods) and budget deficits during recessions (when people spend less on consumer goods). Fifty-one small retailers in a state with a growing economy were recently sampled. The sample showed a mean increase of $2350 in additional sales tax revenue collected per retailer compared to the previous quarter. The sample standard deviation = $425.

a) Find a 95% confidence interval for the mean increase in sales tax revenue.

b) What assumptions have you made in this inference? Do you think the appropriate conditions have been satisfied?

c) Explain what your interval means and provide an example of what it does not mean.
