The confidence interval and the interpretation of it is; CI = (0.34, 0.40) which means that the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).
<h3>What is the confidence interval?</h3>
We are given;
Sample proportion; p = 37% = 0.37
Sample size; n = 1000
The confidence interval for the population proportion, is given by the formula;
CI = p ± z√[(p(1 - p)/n)]
z for Confidence level of 95% is z = 1.96.
Thus;
CI = 0.37 ± 1.96√[(0.37(1 - 0.37)/1000)]
CI = 0.37 ± 0.03
CI = (0.34, 0.40)
Thus, the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).
