TABLE 10-7 To Investigate the Efficacy of a Diet, a Random Sample

question 98

Short Answer

TABLE 10-7
To investigate the efficacy of a diet, a random sample of 16 male patients is drawn from a population of adult males using the diet. The weight of each individual in the sample is taken at the start of the diet and at a medical follow-up 4 weeks later. Assuming that the population of differences in weight before versus after the diet follow a normal distribution, the t-test for related samples can be used to determine if there was a significant decrease in the mean weight during this period. Suppose the mean decrease in weights over all 16 subjects in the study is 3.0 pounds with the standard deviation of differences computed as 6.0 pounds.
-Referring to Table 10-7, a one-tailed test of the null hypothesis of no difference would_____(be rejected/not be rejected) at the ? = 0.05 level of significance.
