a random sample of 40 college professors is selected from all professors at a university. the following list gives their ages.
66, 48, 46, 42, 30, 51, 47, 44, 48, 21, 58, 62, 56, 44, 61,
68, 59, 49, 51, 28, 37, 68, 41, 45, 32, 39, 40, 31, 27, 44,
69, 31, 36, 41, 23, 34, 45, 33, 36, 54.
construct a stem - and - leaf plot for the data. complete parts a. and b.
a. determine the leaves for each corresponding stem. complete the table below.
(use ascending order.)

Explanation:

Step1: Identify the data with stem 6

The data values with stem 6 (i.e., in the 60 - 69 range) are 66, 62, 61, 68, 69.

Step2: Extract the leaves

The units - digit (leaves) of these values are 6, 2, 1, 8, 9.

Step3: Sort the leaves

Sorting 6, 2, 1, 8, 9 in ascending order gives 1, 2, 6, 8, 9.

Answer:

The leaves for stem 6 are \(1,2,6,8,9\)
