The data set represents the number of minutes a sample of 25 people exercise each week. 108 139 120 123, 120, 132, 123, 131, 131, 157, 150,124, 111, 101,135,119,116, 117, 127, 128, 139, 119, 118,114,127
Make a frequency distribution of the data set using five classes. Include class limits, midpoints, boundaries, frequencies, relative frequencies, and cumulative frequencies.
A. Display the data using a frequency histogram and a frequency polygon on the same axes.
B. Display the data using a relative frequency histogram.
C. Describe the distribution's shape as symmetric, uniform, or skewed.
D. Display the data using a stem-and-leaf plot. Use one line per stem.
E. Display the data using a box-and-whisker plot.
F. Display the data using an ogive.
G. Use frequency distribution formulas to approximate the sample mean and the sample standard deviation of the above data set.
