The level of significance is 5% in testing the commercials resulting in in the same mean score cials for different null hypothes Source DF SS MS Factor 4 Error 25 160.0 20.o Total29280.0 120.0 30.0 1.50 a) How many different samples are included in this study? b) Identify the value of the test statistic. c) Find the critical value. d) Identify the P-value. e) What is the conclusion of this study based on the P-value?

Explanation / Answer

Answer

(A) Number of sample= total degree of freedom + 1 = 29 + 1 = 30

so, there are 30 samples

(B) value of test statistic is F = 1.50, given in the data output table above.

so, value of test staistic F is 1.50

(C) Critical F value for degree of freedom for factor = 4 and degree of freedom for error = 25 is 2.76 at 0.05 significance level using the distribution table

(D) P value from the given output table is 0.289

(E) Since the p value of 0.289 is greater than 0.05, which is insignificant. Thus, we can conclude that the different products dont have commerical resulting in the same mean score.
