Which of the following are assumptions underlying repeated-measures ANOVA? Check all that apply. The population variances for each of the treatment groups (cells) are not equal. The values of the repeated variables are constant. The population variances for each of the groups (cells) are equal. The correlations among the pairs of levels of the repeated variable are constant.

You are testing the claim that having lights on at night increases weight gain (abstract). A sample of 10 mice lived in an environment with bright light on all of the time and 8 mice who lived in an environment with a normal light/dark cycle is given below. Test the claim using a 10% level of significance. Assume the population variances are unequal and that the weight changes are normally distributed. Give answers to 3 decimal places. Data available at StatKey, choose Mice Wgt Gain-2e data set Light (x₁) 1.71 4.67 4.99 5.33 5.43 6.94 7.15 9.17 10.26 11.67 What are the correct hypotheses?

8. Hypothesis Test of Equal Variances. Test the given claim. Use a significance level of a = 0.05 and assume that all populations are normally distributed. Claim: IQ scores of statistics students vary less than IQ scores of other students. Statistics students: n = 28, x = 118, s = 10.0 Other students: n = 25, x = 112, s = 12.0

Think about doing an Independent-Measures ANOVA, Step 3.  If the data are as follows, find the SS-between.   GROUP 1 GROUP 2 GROUP 3 1 3 5 3 2 7 2 4 6   A) SS-between = 26.00 B) SS-between = 42.00 C) SS-between = 6.00 D) SS-between = 13.00

"A large candy manufacturer produces, packages and sells packs of candy targeted to weigh 52 grams. A quality control manager working for the company was concerned that the variation in the actual weights of the targeted 52-gram packs was larger than acceptable. That is, he was concerned that some packs weighed significantly less than 52-grams and some weighed significantly more than 52 grams. In an attempt to estimate the variance of the weights of all of the 52-gram packs the manufacturer makes, he took a random sample of n = 20 packs off of the factory line. The random sample yielded a sample variance of 3.5 grams. Use 90% confidence level. What is the confidence interval for the variance of the weight of the candy?"

I understand how to find the f-ratio and generate a conclusion however I am really struggling with the p-values.

Post-hoc tests are necessary for an analysis of variance comparing only two treatment conditions.  t or f
