The main results appear in Table 9-17. Explain these results to a person who has never had a course in statistics.
Events A and B are mutually exclusive events defined on common sample space. If P (A) 0.5 and P (A or B) = 0.70, determine P (B).
By how much does the standard error of x-bar change if the sample is increased to 100?
Is the normality assumption that was made at the beginning valid and what is the probability that the stock on that day closed at less than the mean for that year

Was your test one-tail upper tail, lower tail, or two-tail? Explain why you chose that kind of test in this situation. Explain what your P-value means in this context.
For a hypothesis test about a population proportion or mean, if the level of significance is less than the p-value, the null hypothesis is rejected.
The mean noise level for 24 hospital operating rooms was 56.3 dBA and the standard deviation was 7.5 dBA. At α = .05 can it be concluded that there is a difference in means?
Use a decision tree to describe the possible strategies and the consequences (or payoffs) of each. Show your decision tree.
At alpha = 0.05, is there enough evidence to conclude that proportions vary from those in the study?
Why do you use the chi-square statistic? What type of data is used with chi square analysis?
