Question

A restaurant manager is considering changing the secret sauce on their hamburgers. To decide which recipe to use, she recruits 15 customers and assigns them to 1 of 3 sauce groups (A, B. or C). She then serves them a plain hamburger with the sauce for their group and asks them to rate their satisfaction with the taste of the sauce on a scale from 1 (disgusting) to 5 (delicious) to see if there is a significant (alpha = .05) difference in taste. What is the alternative hypothesis for this Analysis of Variance? Mu A notequalto mu B notequalto mu C there is a significant difference in taste between at least one pair of groups mu A = mu B = mu C there is no significant difference in taste between at least, one pair of groups

Explanation / Answer

Here alternative hypothesis will be " there is significant difference in taste between at least one pair of groups"

Because Null hypothesis will not be satisfied if there is significant difference in taste between at least one pair of groups.
