A sample of 300 FM residents was taken and 135 said their favorite season was summer. Calculate a 99% confidence interval for the proportion of FM residents whose favorite season is summer. What is the lower bound of this interval? (Round your answer to 3 decimal places and enter it with a leading 0. ex: 0.XXX).

The 99% confidence interval for the proportion of FM residents whose favorite season is summer is between (0.376, 0.524).

The lower bound of this interval is 0.376.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

In which

z is the zscore that has a pvalue of .

For this problem, we have that:

99% confidence level

So , z is the value of Z that has a pvalue of , so .

The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval for the proportion of FM residents whose favorite season is summer is between (0.376, 0.524).

The lower bound of this interval is 0.376.
