Question

Healthy Eating Americans appear to be eating healthier. Between

1970 and 2007 the per capita consumption of broccoli increased

1000% from 0.5 to 5.5 pounds. A nutritionist followed a group of people randomly assigned to one of three groups and noted their monthly broccoli intake (in pounds). At α=0.10

, is there a difference in means?

Group A	Group B	Group C
1.9	4.1	2.3
2	4.2	2.5
1	4.3	3.4
1.1	4.5	3.4
1.2	3.3	4.1
1.3	3.4	1.5

State the hypotheses and identify the claim with the correct hypothesis.

H0:μ1=μ2=μ3 claim/do not claim ▼(Choose one)

H1: At least one mean is different from the others. claim/not claim▼(Choose one)

Find the critical value. Use The F Distribution Table to find the critical value. Round the answer to two decimal places.

The critical value is

Compute the test value. Round the intermediate and the final answers to two decimal places.

Make the decision.

reject/do not reject▼(Choose one) the null hypothesis.

Summarize the results.

There is/is not ▼(Choose one) enough evidence to support the claim that there exists a difference in mean broccoli consumption among the three groups.
