A weight loss supplement was administered to 25 obese individuals and after six weeks thedifferences in weight of each subject (starting weight - ending weight) were measured. A test of Ho:0 against H: H > 0 was performed, where u is the population mean weight loss thatwould occur in six weeks if the supplement were given to all obese individuals in the population ofinterest. The test statistic came out to be t = 1.51. Therefore:O The P-value is between .05 and .10, so the evidence that the supplement works is fairly strong.O The P-value is between .05 and .10, so the evidence that the supplement works is fairly weak.O The P-value is between .10 and .20, so the evidence that the supplement works is fairly strong.O The P-value is between.10 and .20, so the evidence that the supplement works is fairly weak.

It is given that the test statistic value t is 1.51.

Answered: A weight loss supplement was…
