The problem and questio

Analysis of Variance by hand. The average number of purchases in three different stores are compared to determine if they are significantly different. The following summary statistics is given for each store. State the null and alternative hypothesis, calculate the F-statistics, p-value, and give a concluding statement.

Table of values: Three different stores

Group	N	Mean	Variance
	4a	35
	4b	5.77
	4b	4.08
	4c	4.08
	4c	20

Answer 1

Hypothesis to be tested

Ho= there is no diffrence in a,b,c groups

H1= there is some diffrence in between a,b,c

Level of significance is 0.05

We see that the value of F calculated is under critical region so the alternative hypothesis is accepted

That is there is significant diffrence in groups.

F Calculated = 40.67

You can check all the other value above
