Question

A graphing calculator is recommended.

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

Home decorating	News	Health	Computer
175	94	88	110
293	98	157	139
167	130	91	103
210	110	110	214
202	108	101	151

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) =

df(denom) =

B) State the distribution to use for the test.

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.)

E) Alpha (Enter an exact number as an integer, fraction, or decimal.)
α =
