Question

3. A test of hypothesis of H₀: μ = 494 versus Hₐ: μ ≠ 494 yields the following test statistic:

\[
z = \frac{\bar{y} - \mu_0}{\frac{\sigma}{\sqrt{n}}} = 0.60
\]

a. What is the p-value for the test of hypothesis?

b. Using the p-value obtained in part a) and an alpha level of .05, what conclusion do you reach regarding the test of hypothesis? Explain.

Use the following data to answer question 8 - 12. A number of studies have claimed evidence that the first-born in a family is, on the whole, more likely to be "successful" than later-borns. A study along this direction compared the IQs of a random sample of 80 first-borns with those of an independent random sample of 105 later-borns. The data are summarized below: Sample size Sample mean Sample SD First-borns 80 112 7.2 Later-borns 105 108 8.0

For a hypothesis test of the claim that the mean amount of sleep for adults is less than 6 hours, technology output shows that the hypothesis test has power of 0.4733 of supporting the claim that μ<6 hours of sleep when the actual population mean is 4.0 hours of sleep. Interpret this value of the power, then identify the value of β and interpret that value.

A weight-lifting coach claims that weight-lifters can increase their strength by taking vitamin E. To test the theory, the coach randomly selects 9 athletes and gives them a strength test using a bench press. Thirty days later, after regular training supplemented by vitamin E, they are tested again. The results are listed below. Use the Wilcoxon signed-rank test to test the claim that the vitamin E supplement is effective in increasing athletes' strength. Use α = 0.05.

A researcher developing scanners to search for hidden weapons at airports has concluded that a new scanner is significantly better than the current scanner. He made his decision based on a test using a = 0.05. Would he have made the same decision at a = 0.20? How about α = 0.01? Explain. Select the statement relating decision making to values of a. O A. His decision would have been the same for a = 0.01 but may have been different for a = 0.20. O B. His decision would have been the same for α = 0.20 but may have been different for α = 0.01. O C. His decision may have been different for both α = 0.01 and α = 0.20. O D. His decision would have been the same for both α = 0.01 and α=0.20.
