The members of the police squad went to different grocery stores to contrast prices of certain items. Team is expiry to perform an analysis of variance supposition experiment to congeal if there is a discrimination in the retail price of groceries at Publix, Winn-Dixie, and Wal-Mart grocery stores.

Team B?s supposal debate is as follows: ?There is n o difference in the price of groceries at Publix, Winn-Dixie, and Wal-Mart grocery stores.?analysis of variance TestThe ANOVA hypothesis testing procedure is used to compare three or more population means simultaneously. It is also used to test whether two sample variances are equal. Team B exit be testing three population means. To be able to use the ANOVA test the data must be distributed normally and the information must be of the ratio or interval level of measurement (Lind, Marchal, & Warthen, 2004).

The beginning(a) step the detective must take to perform the ANOVA test is to affect a hypothesis statement. The must be a zero point hypothesis and an alternative hyp! othesis. The vigor hypothesis is designated as Ho. The null hypothesis equates the ?population parameter to a specification.? (Lind, Marchal, & Wathen, 2004) This hypothesis will also contain an equality. close of the time, researchers conduct tests will the anticipation of rejecting the null hypothesis. The alternative hypothesis is designated as... If you want to get a full essay, order it on our website: BestEssayCheap.com
