Find the sample size suggested by this statement.

The sample size 'n' =15

Step-by-step explanation:

Explanation:-

given data A newspaper article about the results of a poll states: "In theory, the results of such a poll, in 99 cases out of 100

Sample proportion 'p' = 99/100 =0.99

Given Margin of error = 5% =0.05

The margin of error is determined by

The Z-score of 95% of level of significance

Cross multiplication, we get

Squaring on both sides, we get

n = 15.21

Final answer:-

Sample size 'n' = 15
