1. Using the cumulative frequency distribution arrived at in Problem 1, determine
a. P50

b. P25 clinical, health

Problem 1
Convert the grouped frequency distribution of weight losses determined in Problem 10 to a relative frequency and a cumulative frequency distribution. clinical, health

Problem 2
The following scores show the amount of weight lost (in pounds) by each client of a weight control clinic during the last year:

a. Construct a frequency distribution of grouped scores with approximately 10 intervals.

b. Construct a histogram of the frequency distribution constructed in part a.

c. Is the distribution skewed or symmetrical? If it is skewed, is it skewed positively or negatively?

d. Construct a stem and leaf diagram with the last digit being a leaf and the first digit a stem. Repeat stem values twice.

e. Which diagram do you like better, the histogram of part b or the stem and leaf diagram of part d? Explain.
