![a. Use a = .05 to test for a difference among mean comfort scores for the three types of browsers.
Compute the values identified below (to 2 decimals, if necessary).
Sum of Squares, Treatment
89.33
Sum of Squares, Error
24.5
Mean Squares, Treatment
44.67
Mean Squares, Error
1.16
Calculate the value of the test statistic (to 2 decimals, if necessary).
21
The p-value is
less than .01
What is your conclusion?
Conclude that the mean comfort scores are not all the same for the browser groups
b. Use Fisher's LSD procedure to compare the comfort levels of nonbrowsers and light browsers. Use a = .05.
Compute the LSD critical value (to 2 decimals).

What is your conclusion?
Cannot conclude that nonbrowsers and light browsers have different mean comfort scores](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F33160543-4887-41c4-b0aa-028daf39fe31%2F6cd34c3b-9725-441d-ac75-279b82319b13%2F0nt1pi_processed.png&w=3840&q=75)
