A clinical trial for a new drug to treat ADHD reported that side effects were experienced by 19% of patients taking the drug and by 16% of patients taking the placebo. Do a significantly different proportion of patients experience side effects due to the new drug compared with the placebo? Using a calculated test statistic value of z = 2.43 and P-value = 0.015, choose the most correct conclusion (use a significance level of 1%).

Reject H0 since 2 a 0.05 there appears to be a significant difference in the proportions of patients experiencing side effects between the treatment groups Reject Hg since P-value s 0.05 there is evidence that a significantly higher proportion of patients experience side effects with the new drug compared with the placebo Fail to reject H0 since P-value =- 0.01 there is no evidence that a significantlv different proportion of patients experience side effects with the new drug compared with the placebo Fail to reject Ha since P-value s 0.1 there no evidence that a significantly different proportion of patients experience side effects with the new drug compared with the placebo Fail to reject H0 since P-value s 0.01 there appears to be a significantlv different proportion of side effects for patients taking the new drug compared with the placebo
