A pediatrician wants to determine the relation that may exist between a child's height and head circumference. She randomly selects 8 children, measures their height and head circumference, and obtains the data shown in the table. The pediatrician wants to use height to predict head circumference. Compute the linear correlation coefficient between the height and head circumference of a child.

The Department of Motor Vehicles office tried a new customer service system after people complained they were wasting too much time waiting in line. Use the two relative frequency histograms to answer the following questions. Waiting Times at the DMV (OLD SYSTEM) Waiting Times at the DMV (NEW SYSTEM) 50- 50 40 40- 30 30 20 10 0 0 5 10 15 20 25 30 0 5 10 20 25 30 Time Waited OLD (in minutes) 15 Time Waited (in minutes) Comparing the median and the mean for the new system we see that The mean is smaller than the median. The mean is larger than the median. The mean is almost exactly the same as the median. Percent 20 10 0 Percent

Complete the following frequency chart.A frequency chart of temperatures Temperature Frequency Relative Frequency 70 - 74 75 - 79 80 - 84 85 - 89 90 - 94 From the frequency chart, calculate the mean. How does the mean from the raw data (question 7) compare to the mean from the grouped data (question 9)? Use the frequency chart to create a histogram of the daily high temperatures at Cox-Dayton International Airport for June and July 2018. Describe the distribution by shape, center, and spread. Also, state whether there are any outliers.
A medical doctor is interested in determining whether mean body temperatures are different in the morning and at night. Five patients were recruited and their body temperatures were measured first at 8 AM and then again at 10 PM.
