Question: We are doing an ANOVA test with 3 groups. Let n subscript 1 space equals space n subscript 2 space equals space n subscript 3

We are doing an ANOVA test with 3 groups. Let n subscript 1 space equals space n subscript 2 space equals space n subscript 3 space equals space 8. Let mu subscript 1 space equals space 12 comma space mu subscript 2 space equals space 16 and mu subscript 3 space equals space 17. The overall mean is mu equals space 15. Use the formula M S subscript B equals space sum for i of space n subscript i left parenthesis mu subscript i minus space mu right parenthesis squared space divided by space left parenthesis k minus 1 right parenthesis to find the value of the numerator of the ANOVA test statistic
