A person wants to determine which of two routes to drive has the shorter average driving time. Time in minutes for six trips on route A and five trips on route B are as follows: A- 16, 15.7, 16.4,...

A person wants to determine which of two routes to drive has the shorter average driving time.

Time in minutes for six trips on route A and five trips on route B are as follows:

A- 16, 15.7, 16.4, 15.9, 16.2, 16.3.

B- 17.2, 16.9, 16.1, 19.8, 16.7.

a) determine whether you can conclude that the mean score is less for route A. You need to first set

up an alternate and null hypothesis

b) construct a pdf for both sets of data and explain the shape of the graph

c) Determine the error in the sample mean
