Question

Help, very important hw!!!

Answer 1

The stem-and-leaf plot for the distribution is given as follows:

• 1| 9

• 2| 2 2 3 5 7 7 8 8

• 3| 0 1 1 2 3 3 4 5 5 5 7 8 9

• 4| 0 0 1 3

b) From the plot, the correct options are given as follows:

• A typical content is 32 calories per 100 ml.

• The distribution is roughly symmetric.

What is a stem-and-leaf plot?

The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:

4|5 = 45.

For this problem, the observations are given at the top in red, and using each first digit as the key, the stem and leaf plot is:

• 1| 9

• 2| 2 2 3 5 7 7 8 8

• 3| 0 1 1 2 3 3 4 5 5 5 7 8 9

• 4| 0 0 1 3

The mean of these observations is:

(19 + 2 x 22 + 23 + 25 + 2 x 27 + 2 x 28 + 30 + 2 x 31 + 32 + 2 x 33 + 34 + 3 x 35 + 37 + 38 + 39 + 2 x 40 + 41 + 43)/26 = 32(approximately)

The correct statements from the plot are as follows:

• A typical content is 32 calories per 100 ml(due to the mean).

• The distribution is roughly symmetric(13 values below the mean, 13 at or above).
