Worksheet #12 Directions: This worksheet refers to the ANOVA analysis that was on the last worksheet. Refer to the sample statistics from last week to get the sample means and sizes you need. Refer to the ANOVA table from last week to get the MSE and df required for these problems. 1) Because you rejected the null in the ANOVA, you proved that at least one population has a different mean than the others. Use the Fisher's Least Significant Difference procedure (Method 2, as a modified hypothesis test) to find out whether the Merino (group 1) and the Cotton (group 2) means are different from one another, at the a = 0.01 significance level. If they are different, which fleece is warmer? 2) Because you rejected the null in the ANOVA, you proved that at least one population has a different mean than the others. Use the Fisher's Least Significant difference procedure (Method 2, as a modified hypothesis test) to find out whether the Merino (group 1) and the Poly (group 3) means are different from one another, at the a = 0.01 significance level. If they are different, which fleece is warmer
