Answer :
Final answer:
To find the 99% confidence interval of the mean high temperature of towns, use the t-distribution and calculate the sample mean, sample standard deviation, and t-value.
Explanation:
To find the 99% confidence interval of the mean high temperature of towns, we will use the t-distribution since the population standard deviation is unknown. The formula for the confidence interval is:
CI = sample mean ± (t-value) * (sample standard deviation / sqrt(sample size))
First, calculate the sample mean and sample standard deviation of the data. Then, find the t-value for a 99% confidence level with (n - 1) degrees of freedom, where n is the sample size. Finally, substitute the values into the formula to find the confidence interval.
