Question: We are doing an ANOVA test with 4 groups. Let n subscript 1 space equals space n subscript 2 space equals space n subscript 3

We are doing an ANOVA test with 4 groups. Let n subscript 1 space equals space n subscript 2 space equals space n subscript 3 equals n subscript 4 equals space 5. Let s subscript 1 space equals 2 comma s subscript 2 space equals 5 comma s subscript 3 equals 3 and s subscript 4 equals 4. The overall sample size is N = 18. Find the value of the denominator of the ANOVA test statistic. Since all sample sizes are equal, the denominator will be M S subscript W equals space 1 fourth s subscript 1 superscript 2 plus 1 fourth s subscript 2 superscript 2 plus 1 fourth s subscript 3 superscript 2 plus 1 fourth s subscript 4 superscript 2 space. Round your answer to one decimal place
