Reference no: EM1311539

For each of the following problems, assume that the homogeneity of variance assumption has not been met and that you will need to use the adjusted Welch statistic. For each problem, compute a Welch F-statistic and determine whether or not significant differences exist among the treatment conditions.

Low Noise	Moderate Noise	Loud Noise
10	5	6
11	4	3
13	4	3
12	5	5

1. What is your computed F-statistic?

2. What was the critical F value chosen?

3. Is there a significant difference between the groups?
