Find the standard deviation, s, of sample data summarized in the frequency distribution table below by using the formula below, where x represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 11.1. S= |n[Σ(f•x?)]-[Σ«•x] n(n-1) Interval Frequency Standard deviation = 30-39 1 40-49 2 (Round to one decimal place as needed.) 50-59 3 60-69 1 70-79 13 80-89 36 90-99 29

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.
