The Economic Policy Institute periodically issues reports on wages of entry-level workers. The institute reported that entry-level wages for male college graduates were $21.68 per hour and for female college graduates were $18.80 per hour in 2011. Assume that the standard deviation for male graduates is $2.30, and for female graduates it is $2.05. What is the sampling distribution of for a random sample of 50 male college graduates? What is the sampling distribution of for a random sample of 50 female college graduates? In which of the preceding two cases, part (a) or part (b), is the standard error of smaller? Why?

Return to the waiting times given for the physicians office in Problem 19. a. Considering only offices without a wait-tracking system, what is the z-score for the 10th patient in the sample (wait time 5 37 minutes)? b. Considering only offices with a wait-tracking system, what is the z-score for the 6th patient in the sample (wait time 5 37 minutes)? How does this z-score compare with the z-score you calculated for part a? c. Based on z-scores, do the data for offices without a wait-tracking system contain any outliers? Based on z-scores, do the data for offices without a wait-tracking system contain any outliers? 19. Suppose that the average waiting time for a patient at a physicians office is just over 29 minutes. To address the issue of long patient wait times, some physicians offices are using wait-tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less time in waiting rooms. The following data show wait times (in minutes) for a sample of patients at offices that do not have a wait-tracking system and wait times for a sample of patients at offices with such systems. a. What are the mean and median patient wait times for offices with a wait-tracking system? What are the mean and median patient wait times for offices without a wait-tracking system? b. What are the variance and standard deviation of patient wait times for offices with a wait-tracking system? What are the variance and standard deviation of patient wait times for visits to offices without a wait tracking system? c. Create a box plot for patient wait times for offices without a wait-tracking system.

Sample Evaluation. Gloria Bush has performed a sampling plan to estimate the numberof children per household in her neighborhood. In doing so, she established a 10 percentacceptable level of sampling risk and found a sample estimate of 2.5 children per household.Based on the acceptable level of sampling risk, she calculated a precision of 0.7 children perhousehold.Required:a. Define the terms precision and reliability. How are these terms related?b. What is the precision interval in this example? What statement can Bush make based onher sample evidence?c. Assume that she desires a lower sampling risk (5 percent). How will this affect the precision interval?d. If she is interested in knowing whether the number of children per household exceeds1.5 children, how would you advise her based on the following outcomes? In all cases,assume that the sample estimate is 2.5 children per household.1. Reliability = 90 percent; precision = 0.7 children per household.2. Reliability = 95 percent;…
