The following table lists the number of pages in four different types of magazines.

Home decorating	News	Health	Computer
168	84	79	99
284	89	151	131
161	121	84	92
202	104	97	205
192	99	94	140

Using a significance level of 5%, test the hypothesis that the four magazine types have the same average length. (Let 1 = Home decorating, 2 = News, 3 = Health and 4 = Computer.)

A. Enter an exact number as an integer, fraction, or decimal.
df(num) =
B. Enter an exact number as an integer, fraction, or decimal.
df(denom) =
C. What is the test statistic? (Round your answer to two decimal places.)
D. What is the p-value? (Round your answer to four decimal places.)

F. What is the alpha? (Enter an exact number as an integer, fraction, or decimal.)

Answer 1

The statistical software output for this problem is:

From above output:

a) df(Num) = 3

b) df(Denom) = 16

c) Test statistic = 8.31

d) p - Value = 0.0015

e) Alpha = 0.05
