The stem-and-leaf plot for the distribution is given as follows:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
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.
<h3>What is a stem-and-leaf plot?</h3>
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 <u>first digit as the key</u>, the stem and leaf plot is:
- 3| 0 1 1 2 3 3 4 5 5 5 7 8 9
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).

Move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2
c=2.12 or -0.12
7/8 is closest to 1 and 4/9 is closest to 0
