A business magazine did a study to determine how much more a supervisor makes than other employees. They sent a questionnaire to companies in the San Diego area and asked the average amount of money their supervisors make and the average amount their regular employee make. Our data is made up of the few companies that responded to the questionnaire. If we let population 1 represent supervisors monthly salary and population 2 represent regular employees monthly salary, we obtained a 95% confidence interval estimate of the difference (supervisors – regular) to be (+$457.18 , +$2160.37). Determine whether the following statements are true or false interpretations of this confidence interval.  b. The confidence interval tells us that regular employees make an average of $457.18 and supervisors make an average of $2160.37.

In a large Midwestern university (the class of entering freshmen is 6000 or more students), an SRS of 100 entering freshmen in 1999 found that 20 finished in the bottom third of their high school class. Admission standards at the university were tightened in 2000. In 2001, a SRS of 100 entering freshmen found that 10 finished in the bottom third of their high school class. Is there evidence that the proportion of freshmen who graduated in the bottom third of their high school class in 2001 has been reduced, as a result of the tougher admission standards adopted in 2000, compared to the proportion in 1999?
