The data set represents the number of minutes a sample of 27 people exercise each week 108 139 120 123 120 132 123 131 131 157 150 124 111 101 135 119 116 117 127 128 139 119 118 114 127 142 130 1.- Construct a frequency distribution for the data set. Include class limits, midpoints boundaries, frequencies, and cumulative frequency. Describe each graph. 2.- Display the data, using a frequency histogram and a frequency polygon. 3.- Display the data using a stem and leaf plot. 4.- Display the data, using a box and whisker plot. 5.-Make a pie chart graph.6.- Make a dot plot 7.- Calculate the sample mean, median, mode and standard deviation.8.- Find the coefficient of variation of the data set.9.-Find the confidence interval for the mean, using a level of confidence for the mean of 0.95. 10.- The coach claims that mean time the 27 people exercise is more than 125 minutes each week. Can you support the claim , using a level of significance of 0.05?
