In Question 10.5 on page 231, it was concluded that the mean salary among the population of female members of the American Psychological Association is less than that ($82,500) for all comparable members who have a doctorate and teach full time.

(a)Given a population standard deviation of $6,000 and a sample mean salary of $80,100 for a random sample of 100 female members, construct a 99 percent confidence interval for the mean salary for all female members. Switch to an interval having a lesser degree of confidence, such as 90 percent or 75percent. Weight of 33.09 ounces for a random sample of 36 candy boxes, construct

a 95 percent confidence interval.

-Confidence Interval:

0.1

- Range for the true population mean:

32.99 to 33.19
