Question

A simple random sample of 20 days was selected and the amount of food that Parsnip ate each day was recorded. The data is listed below. 33 38 32 49 19 23 14 18 14 51 33 19 12 39 40 37 17 18 34 40 Calculate the mean, median, range, standard deviation, and IQR of this data. Please write the answers in the box below. Construct an appropriate stem-and-leaf plot to graphically display this data. To do so, type the stems down the left edge of the box, and next to each space over three (3) times. Then write the leaves next to the appropriate stems. It is not necessary to draw a line to separate the stems and the leaves. Use the stem-and-leaf plot and appropriate statistics to completely describe the distribution of the amount of food that Parsnip ate each day.

Answer 1

solution (2 Here from the given data n=20 mean = Ex = 580 = 29. median = entifth u=20+1) V = 10.5th U= 32.5 Range = max- min = 51-12=39 Standard deviation (5)= 26- 12-1352 Q1 = (n+15th U= 5.25th u= 5thuto.25 (6thu- 5th=18 23 = 3 mats) th= 15-75th V = 38-25 IQR = Qz-Q1 = 38-75-18 = 20-75 nal
