Question

Three commuters from Sackville wanted to determine what affected the time it took to get to Dalhousie in the morning. An experiment was conducted using 2 possible routes (A and B) and the three different drivers. For each route-driver combination, three trips were timed (in minutes). The data and partial ANOVA table are shown below. Driver Route A Route B 32 29 35 29 26 26 2 1 34 33 40 42 35 3 42 35 34 45 45 45 Source DF SS MS F P Driver 2 417 208.5 Route 1 18 18 Interaction 2 129 64.5 6.143 0.015 Error 12 126 10.5 Total 17 690 Note that interactions are significant at the a 0.10 level. Use the Minitab command invcd f (or ato in R) to generate the correct critical t-value to use for multiple comparisons among the ce means What is the number of possible pairs of (Driver-Route) cell means? 2 pt(s) Submit Answer Tries 0/3 what is the value of a nter at least four significant digits after the decima 1 pt(s Submit Answer Tries 0/3 The critical t-value has a student's t distribution with how many degress of freedom? 1 pt(s Submit Answer Tries 0/3

Explanation / Answer

1.there are 3×2 cells in the table, and therefore6C2=6!/2!4!= 15

2.Alpha=0.10.

*=/15 =.1/15 =.0067

3.The value for t uses 12 degrees of freedom

4.The value for t uses 12 degrees of freedom */2 =.0033, and is 3.27

Hope this will helps you. THANKS:)
