Thank you 

1-a. A random sample of 900 13- to 17-year-olds found that 411 had responded better to a new drug therapy for autism. Let p be the proportion of all teens in this age range who respond better. (1). A 95% confidence interval for p is a. 0.46 + 0.017. b. 0.46 + 0.027. c. 0.46 + 0.033. d. 0.46 + 0.248. (2). Suppose you wished to see if the majority of teens in this age range respond better. To do this, you test the following hypotheses Ho : p = 0.50 versus H. : p > 0.50. The p-value of your test is a. greater than 0.10. b. between 0.05 and 0.10. c. between 0.01 and 0.05. OT PO/Share d. below 0.01.
