Exo 1: The number of grams of fat per serving for three different varieties of frozen meals from several manufacturers is measured and a partial ANOVA table is provided below. nl=6, n2-9 and n3-7. Complete the ANOVA table. At the 0.05 significance level, is there a significant difference in mean fat content for the three varieties? Assume the assumptions for the test are met. Which frozen meal has the highest content of fat? GROUP ERROR TOTAL DOF SUM SQUARE MS 316 PVALUE Exo 2: Prices (rounded to the closest dollar amount) of men's, women's, and children's sportswear shoes were compared by obtaining random samples of 18 shoes each. The variances of the samples are homogeneous and the distributions are assumed to be approximately normal. 1. Use the information provided to test at a-.05 whether there is a difference in mean shoe prices for the three types of shoes. SSG-2210.1 SSW-5083.4 2. The means for the three groups are as follows: Women's shoes $48.78; Men's shoes S60.33; Children's shoes $45.39. Perform the necessary tests to find where the difference lies. State your overall inference. Exo 3: A farmer tested three kinds of seeds to grow pumpkins with the weights (in pounds) of harvested pumpkins in each sample given below. Test at a-.05 whether there is a difference in the mean weights of different pumpkins. If you find a difference, perform pairwise tests to determine where the difference lies. Assume the distributions are normal and variances are equal. Seod A Sond Seed C 123 142 114 114 115 11.4 14 1204 136 108 12 12 124 119
