Show calculations and supporting reasons for your conclusion.

Solution

Sol)

NULL HYPOTHESIS: All the means of four types are equal

ALTERNATIVE HYPOTHESIS: Al the means of four types are not equal

LEVEL OF SIGNIFICANCE: 1%

TEST STATISTIC:

We Use Anova One way (F test) to find the difference between several means

From the EXCEL

CONCLUSION:

F cal= 10.91 and F critical value at 1% is=4.377

Hence F cal > F critical value, then we reject the null hypothesis.

ie., All the four groups are having different means.
