Question

In order to shorten the time it takes Jim to bake his favorite cookies, he designed an experiment to test the effect of eggs and sugar on the cooking time. Specifically he tested 3 different batches of cookies and measured how many minutes it took for the same amount of cookie dough to bake. This ANOVA table follows: State the hypotheses about the cookie dough (both numerically and in words) The results of a student's experiment on the effectiveness of four different types of noise filters are as followed:

Explanation / Answer

Question 11

The null and alternative hypotheses for the given ANOVA test are given as below:

Null hypothesis: H0: There is no any significant difference in the average time in minutes for the same amount of cookie dough to bake for three different batches.

Alternative hypothesis: Ha: There is a statistically significant difference in the average time in minutes for the same amount of cookie dough to bake for three different batches.

H0: µ1 = µ2 = µ3 versus Ha: µ1 µ2 µ3 or at least two means are different

Question 12

The null and alternative hypotheses for the given ANOVA test are given as below:

Null hypothesis: H0: There is no any significant difference in the average effectiveness of four different types of noise filters.

Alternative hypothesis: Ha: There is a statistical difference in the average effectiveness of four different types of noise filters.

H0: µ1 = µ2 = µ3 = µ4 versus Ha: At least two means are different
