Question

I wanted to find an estimation for how many Americans cancelled their HBO subscriptions after the series finale of Game of Thrones (guilty). A poll I found online from 1,349 people was taken to determine the answer. Given this data, roughly 499 out of 1349 were either “somewhat likely” or “very likely” to cancel their subscription. Construct a confidence interval given a 91% level of confidence.

Answer 1

= X / n = 499/1349 = 0.3699

n = 1349



Lower Limit =
upper Limit =
91% Confidence interval is ( 0.347619 , 0.392189 )

( 0.3476 < P < 0.3922 )

91% confidence interval that Americans cancelled their HBO subscriptions after the series finale of Game of Thrones (guilty) is  ( 0.3476 < P < 0.3922 ).
