A medical researcher gives a new muscle relaxant to 200 patients and determines that 156 have benecial results. The muscle relaxants currently in use have a success rate of 0.7. Test whether the new drug is superior to the existing drugs. a) Choose the null hypothesis, by recording the letter of your choice from below 0 H0: 5 = 0.78 O HO: p = 0.7 O HO: p > 0.78 O HO: p > 0.7 12355: Tries 0/1 b) Choose the alternative hypothesis, by recording the letter of your choice from below 0 Ha: p > 0.78 0 Ha: p > 0.7 0 Ha: p > 0.7 0 Ha: p = 0.78 11523852.\": Tries 0/1 c) What is the value of the test statistic? Give your answer to two digits past the decimal. C E Tries 0/5 d) What is the P value or signicance probability? Give your answer to 3 places past the decimal, without a leading zero. E Tries 0/5 e) Choose the appropriate conclusion. 0 no evidence against the null hypothesis 0 weak evidence against the null hypothesis 0 strong evidence against the null hypothesis 0 very strong evidence against the null hypothesis Tries 0/2
