Question

Figure out the confidence interval or hypothesis

test problem, using a significance level not previously used Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.....


Route 1: Chesterfield VA, Henrico VA, via 195 N with toll attached

Route 2: Chesterfield VA, Henrico VA, via Parham road with no toll.

 

I wanted to test if Route 1 had a shorter mean travel time than Route 2. I attempted to decide to test this theory, by collecting ten sample commute times from each:

 

Route 1 Sample Commute Times (all in minutes)

40, 45, 30, 28,32,34,37,42,48,41

 

Route 2 Sample Commute Times (all in minutes)

60, 65,50,55,58,45,51,32,34,30

 

The parameters that I am investigating are

 

µ1= Mean Commute Time for Route 1

µ2= Mean Commute Time for Route 2

 

Then my hypothesis test would be

Ho: µ1-µ2=0

H¹: µ1-µ ≤ 0

 

To test my hypotheses, I would need to plug the data into stat crunch, by putting in the commute times of each route in VAR 1 and VAR 2.

 

Determine which of these routes, would have a lower commute time.
