A certain drug is used to treat asthma. In a clinical trial of the drug, 30 of 260 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 0.01 significance level to complete parts (a) through (e) below. 1-PropZTest prop<0.1 a. Is the test two-tailed, left-tailed, or right-tailed? Right tailed test Two-tailed test Left-tailed test b. What is the test statistic? z = 0.83 (Round to two decimal places as needed.) c. What is the P-value? P-value= (Round to four decimal places as needed.) z=0.826898231 p-0.7958526269 p=0.1153846154 n-260
