Question

The table below is based on the Stem and leaf diagrams showing dividend yields ($) for common stocks.

Dividend Yielded ($) Frequency
20-24 5
25-29 6
30-34 14
35-39 X
40-44 7
45-49 5



Use the stem and leaf diagram below to determine the value of x.

and then Using the table above to calculate the sample mean, the mode and the sample variance of the dataset.

Stem-and-Leaf Display
N = x Leaf Unit = 1.0
5      2     33444
11    2     668899
(14)  3    00112223344444
