Test the claim about the differences between two population variances of and oz at the given level of significance a using the given sample statistics. Assume that the sample statistics are from independent samples that are randomly selected and each population has a normal distribution. Claim of so, a=0.01 Sample statistics s = 895, n = 13, s= 253, n2 = 4 Find the null and alternative hypotheses ● A. Ho o sol Ов. Но оо, H₂ 0 0 H₂0 5022 Ос. Но, <a OD. Ho 07 207 / H₂0² 203 H₂0²0 Find the critical value (Round to two decimal places as needed) Find the test statistic. (Round to two decimal places as needed) Choose the correct conclusion below

k point(s) possible Fair stain G removal tyls The table to the night shows the cost per ounce (in dollars) for a random sample of toothpastes exhibiting very good stain removal good stain removal, and fair stain removal. At a=0.01, can you conclude that the mean costs per ounce are different? Perform a one-way ANOVA test by completing parts a through d. Assume that each sample is drawn from a normal population, that the samples are independent of each other, and that the populations have the same variances me Very good stain removal 0.50 0.41 0.51 1.55 0.48 0.35 Good stain removal 0.98 2.68 0.46 0.64 0.75 1.35 0.34 1.24 0.44 (a) Identify the claim and state Ho and H. Choose the correct answer below O A. Ho H = 12 = 14₂ = 14 - 15 16 B. Ho. At least one mean is different from the others. (claim) Ha Al least two means are different from the others. (claim) Ha H1 H2 = 13 = 14-15-16 02. Ho | 1 | 2 | 3 OD. Ho H1 H2 H3 (claim) Ha At least one mean is different from the others. (claim) Ha: At least one mean is different from the others. (b) Identify the degrees of freedom for the numerator and for the denominator, determine the critical value and determine the rejection region The degrees of freedom for the numerator, df Niis and the degrees of freedom for the denominator, d.f.p.is The critical value is Fo=D (Round to two decimal places as needed) The rejection region is (Round to two decimal places as needed)
