Expert Solution
Step 1

The 99% confidence interval for the true population mean watermelon weight is obtained below:

The value of mean weight is 41 ounces, population standard deviation is 4 ounces and sample size (n) = 49

Critical value:

From the standard normal distribution table, for the 99% confidence level the critical values is (z*) 2.58.
