Answer

Explanation:

Step1: Count total number of data - points

Count the number of leaves in the stem - and - leaf plot. There are (4 + 6+7 + 3+3 + 1=24) data - points.

Step2: Calculate the position of the 75th percentile

Use the formula (L=(n + 1)\times p), where (n = 24) (number of data - points) and (p = 0.75). So (L=(24 + 1)\times0.75=25\times0.75 = 18.75).

Step3: Arrange data in ascending order and find the value

Arrange all the data values from the stem - and - leaf plot in ascending order. The 19th value (since (L = 18.75) and we round up) in the ordered data - set is 35.

Answer:

35 pages.
