Question

Assume that a sample is used to estimate a population proportion p. Find the 98%
confidence interval for a sample of size 108 with 38 successes. Enter your answer as
an open-interval (i.e., parentheses) using decimals (not percents) accurate to three
decimal places.
98% C.I. =

Expert Solution

Step 1: Determine the given data

From the provided information,

n=108 and x=38 successes.

Confidence level is 98%

$p with hat on top equals x over n equals 38 over 108 equals 0.352$
