Determine whether the stated sample size n is large enough, for the given value of p0, to use the methods of this section to perform a test of hypothesis for p.
1. n = 500, p0 = 0.05
2. n = 80, p0 = 0.18
3. n = 100, p0 = 0.40
4. n = 300, p0 = 0.75
5. n = 120, p0 = 0.01
Make it an experiment! In the following observational studies, describe changes that could be made to the data collection process that would result
Suppose the significance level is changed to α = 0.01. Will the probability of a Type II error increase, decrease, or remain the same?
A normal population has a mean of 60 and a standard deviation of 3. You select a sample of 36. Compute the probability the sample mean is (Round z values to 2 decimal places and final answers to 4 decimal places):
Carry out the Wilcoxon rank sum test. State hypotheses and give the rank sum W for high-progress readers, its P-value, and your conclusion. Do the t and Wilcoxon tests lead you to different conclusions?

Construct and interpret a 99% confidence interval for the difference in the true proportions of men and women aged 19 to 25 who live in their parents' homes.
At the 0.05 level, is the 40% rate significantly greater than the 35% that had been occurring in the past, or might this higher rate be simply due to chance variation? Identify and interpret the p-value for the test.
Use the 68-95-99.7 Rule to sketch a curve for this distribution, marking off the weights that are within 1, 2, and 3 standard deviations of the mean.
