A researcher wants to estimate the true proportion of Americans who suffer side-effects after taking a particular medication. A 99% confidence interval for the true proportion of Americans who suffer side-effects after taking the particular medication was found to be (0.024, 0.160). If a hypothesis test is conducted with the hypotheses, Ho: p = 0.10 vs Ha: p ≠≠ 0.10 , what would be the most likely conclusion? a. There is very strong evidence that p ≠0.10. b. There is strong evidence that p ≠ 0.10. c. There is little to no evidence that p ≠ 0.10. d. Cannot tell
