Question

A certain drug is used to treat asthma In a clinical trial of the drug, 26 of 256 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 10% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.05 significance level to complete parts (a) through (e) below. 1 - Prop Test prop <0.1 z=0.083333333 p0.5332067517 p=0.1015625000 n-256 a. Is the test two-tailed, left-tailed, or right-tailed? Left-tailed test Two-tailed test Right tailed test b. What is the test statistic? ZE (Round to two decimal places as needed.)
