2. b. Test statistic = ?c. P-value = ? d. Reject/Accept null hypothesis ? A certain drug is used to treat asthma. In a clinical trial of the drug, 18 of 289 treated subjects experiencedheadaches (based on data from the manufacturer). The accompanying calculator display shows results froma test of the claim that less than 11% of treated subjects experienced headaches. Use the normal distributionas an approximation to the binomial distribution and assume a 0.05 significance level to complete parts (a)through (e) below.1-PropZTestprop < 0.11z = 2.592531243p=0.0047636264p=0.0622837370n = 289

In the past, the mean running time for a certain type of flashlight battery has been 9.6 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean running time has decreased as a result. A hypothesis test is to be performed. Determine the null and alternative hypotheses. A. H0: µ ¥ 9.6 hours and H1: µ = 9.6 hours B. H0: µ = 9.6 hours and H1: µ ¥ 9.6 hours C.
