27.Suppose we wish to test H0: 47 versus H1: > 47. What will result if we conclude that themean is greater than 47 when its true value is really 52? a)We have made a Type I error.b)We have made a Type II error.c)We have made a correct decisiond)None of the above are correct.ANSWER:c TYPE: MC DIFFICULTY: Moderate KEYWORDS: one-tailed test, conclusion 28.How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: X = 52, s= 22. Give the null and alternative hypotheses to determine if the number of tissues used during a cold is less than 60. 60. 60. 60. 52. TYPE: MC DIFFICULTY: Moderate KEYWORDS: one-tailed test, form of hypothesis, form of hypothesis, mean, t test 29.How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: X = 52, s= 22. Using the sample information provided, calculate the value of the test statistic.

Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: X = 52, s= 22. Suppose the alternative we wanted to test wasH1:60. State the correct rejection region for = 0.05.

Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: X = 52, s= 22. Suppose the test statistic does fall in the rejection region at = 0.05. Which of the following decision is correct? a)At = 0.05, we do not reject H0b)At = 0.05, we reject H0c)At = 0.05, we accept H0d)At = 0.10, we do not reject H0ANSWER:b . . . .
