**Problem Statement**Assume that a sample is used to estimate the mean tip earned by a serving staff at a diner. Find the margin of error (M.E.) that corresponds to a sample of size 23 servers with a mean of $76.33 and a standard deviation of $6.23 at a confidence level of 99%.Report M.E. accurate to one decimal place because the sample statistics are presented with this accuracy.**Calculation**M.E. = $ [_______]**Explanation**This problem involves calculating the margin of error for the mean tip based on a sample of servers. The given data includes:- Sample size: 23- Sample mean: $76.33- Standard deviation: $6.23- Confidence level: 99%The goal is to determine the margin of error validated to one decimal place.

Given n=23 Mean=76.33 Standard deviation=6.23

Answered: Assume that a sample is used to…

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 42 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Make B is 45 feet. Assume the population standard deviation is 4.4 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) rari rz (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is/are (Round to three decimal places as needed. Use a comma to separate answers as needed.)
