Question

1. A paper on men's and women's eating behaviors describes an experiment in which 74 men were assigned at random to one of four treatments.

viewed slides of fit, muscular men
viewed slides of fit, muscular men accompanied by diet and fitness-related text
viewed slides of fit, muscular men accompanied by text not related to diet and fitness
did not view any slides

The participants then went to a room to complete a questionnaire. In this room, bowls of pretzels were set out on the tables. A research assistant noted how many pretzels were consumed by each participant while completing the questionnaire. Data consistent with summary quantities given in the paper are given in the table.

Do these data provide convincing evidence that the mean number of pretzels consumed is not the same for all four treatments? Test the relevant hypotheses using a significance level of 0.05. (Let ?₁, ?₂, ?₃, and ?₄ be the true mean number of pretzels consumed for the four different treatments.)

State the appropriate null and alternative hypotheses.

H₀ : ?₁ = ?₂ = ?₃ = ?₄
H_a : all four of the ?_i's are different

H₀ : all four of the ?_i's are differentH_a : ?₁ = ?₂ = ?₃ = ?₄

H₀ : ?₁ = ?₂ = ?₃ = ?₄
H_a : at least two of the four ?_i's are different

H₀ : at least two of the four ?_i's are different

H_a : ?₁ = ?₂ = ?₃ = ?₄

H₀ : ?₁ = ?₂ = ?₃ = ?₄

H_a : at least three of the four ?_i's are different

Find the test statistic and P-value.

Round your test statistic to two decimal places and your P-value to three decimal places.)

P-value=

State the conclusion in the problem context.

We reject H₀. The data do not provide convincing evidence that the mean number of pretzels consumed is not the same for all four treatments.

We fail to reject H₀. The data provide convincing evidence that the mean number of pretzels consumed is not the same for all four treatments.

We fail to reject H₀. The data do not provide convincing evidence that the mean number of pretzels consumed is not the same for all four treatments.

We reject H₀. The data provide convincing evidence that the mean number of pretzels consumed is not the same for all four treatments.
