An experiment has a sinale factor with 3 aroups and 5 values in each aroup. In determining the among-group variation, there are 2 degrees of freedom. In determining the within-group variation, there are12 degrees of freedom In determining the total variation, there are14degrees of freedom. Also, note that SSA = 42 SsW 84, SST= 126, MSA = 21, MSW = 7, and FSTAT = 3. Complete parts (a) through (d). a. Construct the ANOVA summary table and fill in all...

PLEASE ANSWER ALL QUESTIONS 1. A large department store examined a sample of the 24 credit card sales and recorded the amounts charged for each of three types of credit cards: MasterCard, Visa, and Discover. Six MasterCard sales, ten Visa, and eight Discover sales were recorded. The store used an ANOVA to test if the mean sales for each credit card were equal. What are the degrees of freedom for the F statistic? Select one: a. 2 in the numerator,...

use first chart to answer questions 18-20 D Question 18 5 pts Suppose 20 hypertensive patients are assigned at random to each of four therapy groups, and the change of in diastolic blood pressure (DBP) is noted in these patients after a 1-month period. We want to see whether there is any difference in mean changes in DBP among the therapy groups. The results are given in the following table (please use this table to answer questions 18 through 20):...
6 questions need to be answered. please answer all thank you!! 8. Tukey's HSD test A Aa Sleep apnea is a disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavior problems, including hyperactivity, inattention, and aggression. A common treatment for pediatric sleep apnea is the surgical removal of enlarged tonsils and adenoids that are obstructing the airways. Suppose researchers at a sleep clinic are interested in the effect of surgical treatment...
Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
