Based on a random sample of n = 32 online orders at Guiseppe's Pizza, the mean amount of the order (x) is $25.34 with a standard deviation (s) of $3.168. Find the 99% confidence interval for the population mean amount of the order (in dollars). Follow the steps below. a) What is the value here? b) What is the degrees of freedom (df)? c) Find the corresponding taas value from the t-distribution table. d) Compute the margin of error (E) using the formula below. 8=1() Lower limit: Upper limit: E e) Compute the 99% confidence interval for the population mean amount of the order.
