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) explain the type of data you have here and the hypothesis test you would use to determine the
difference between the two routes
b) 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
c) construct a pdf for both sets of data and explain the shape of the graph
d) calculate a 95% confidence interval for each set of data.
e) Determine the error in the sample mean
