Give the hypothesis statements calculations comparison value

Give the hypothesis statements, calculations, comparison values, and conclusions (including supporting reasons for conclusions).

Solution

NULL HYPOTHESIS: All the means of 3 types(Middle schools teachers, High school teacher, college teachers) are equal

ALTERNATIVE HYPOTHESIS: All the means of 3 types(Middle schools teachers, High school teacher, college teachers) are not equal

LEVEL OF SIGNIFICANCE: 5%

TEST STATISTIC:

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

From the EXCEL

CONCLUSION:

F cal= 2.5165 and F critical value at 5% is=3.68

Hence F cal < F critical value, then we accept the null hypothesis.

ie., All the means of 3 types(Middle schools teachers, High school teacher, college teachers) are equal
