A certain drug is used to treat asthma. In a clinical trial of the drug, 22 of 266 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 11% 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. A. Is the test two-tailed, left-tailed, or right-tailed? B. What is the test statistic? Z=[ ] (Round to TWO decimal places as needed) C. What is the P-value? P-value= [ ] (Round to FOUR decimal places as needed) D. What is the null hypotheses, and what do you conclude about it? Decide weather to reject the null hypothesis. E. What is the final conclusion? |

A clinical trial is conducted on a specific drug used to treat
severe migraines and it is noted that approximately 25% of
individuals in the study fail to respond to the drug and the
medication appears to give them severe episodes of nausea and
vomiting. Upon further examination it is revealed that these
individuals carry a genetic marker, and the individuals who did not
experience the side effects of nausea and vomiting did not have the
same marker as those...
