A nutrition expert claims that the average American is overweight. To test his claim, a random sample of 29 Americans was selected, and the difference between each person's actual weight and idea weight was calculated. For this data, we have x = 15.7 and s = 29.9. Is there sufficient evidence to conclude that the expert's claim is true? Carry out a hypothesis test at a 9% significance level. Hint: Pay attention to the variable being measured: the difference between actual weight and ideal. A positive value indicates that the person is overweight. %3D A. The value of the standardized test statistic (give to 3 decimal places): B. The p-value is (give to 4 decimal places): C. Your decision for the hypothesis test: O A. Reject Ho. O B. Do Not Reject Ho. C. Do Not Reject Ha. O D. Reject Ha.
