TABLE 10-6 To Investigate the Efficacy of a Diet, a Random Sample

question 263

Short Answer

TABLE 10-6
To investigate the efficacy of a diet, a random sample of 16 male patients is selected 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 four 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 10-6, if we were interested in testing against the two-tail alternative that μ is not equal to zero at the α = 0.05 level of significance, the null hypothesis would ________ (be rejected/not be rejected).
