Answer 3

The data set is 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 (make first lower limit start at 101), midpoints, frequencies, boundaries, relative frequencies, and cumulative frequencies.  

Display the data using a frequency histogram. Describe any pattern.

Display the data using a frequency polygon.

Display the data using a relative frequency histogram.

Display the data using ogive. Describe any pattern.  

Display the data using Unordered Stem-and-Leaf Plot.

Display the data using Ordered Stem-and-Leaf Plot.  

Display the data using a dot plot.  

Describe the distribution’s shape as symmetric, uniform, or skewed.

Determine the mean, median, and mode of the sample using the raw data.
