Question

From a large number of actuarial exam scores, a random sample of 300 scores is selected, and it is found that 204 of these 300 are passing scores. Based on this sample, find a 95% confidence interval for the proportion of all scores that are passing. Then find the lower limit and upper limit of the 95% confidence interval.

Step 1

The sample proportion (\( \hat{p} \)) is the number of successes (passing scores) divided by the total number of observations in the sample. In this case, there are 204 passing scores out of 300 total scores. Thus, the sample proportion is: \[ \hat{p} = Show more…
