An independent consumer group states that, among all people with depression who use a new antidepressant, the proportion p of people who find relief from depression is 65%. A random sample of 215 patients who use the drug is selected, and 120 or them find relief from depression. Based on these data, can we reject the consumer group's claim at the 0.01 level of significance? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
The null hypothesis:
The alternative hypothesis:
The type of test statistic:(Choose one)
The value of the test statistic: (Round to at least three decimal places.)
The p value (Round to at least three decimal places)
Can we reject the claim that the proportion of people who find relief from depression using the new antidepressant is 65% Yes No
