To test Ho: = 46 versus Hy: p # 46, a simple random sample of size n =35 is obtained. Complete parts (a) through (c) below. Click the icon to view the table of critical t-values. (a) Does the population have to be normally distributed to test this hypothesis by using t-distribution methods? Why? O A. No-there are no constraints in order to perform a hypothesis test. O B. Yes-since the sample size is at not least 50, the underlying population does not need to be normally distributed. O C. No-since the sample size is at least 30, the underlying population does not need to be normally distributed. O D. Yes-the population must be normally distributed in all cases in order to perform a hypothesis test. (b) Given sample evidence, x=49.1 and s=7.2, construct a 99% confidence interval to test the hypothesis The lower bound is The upper bound is (Round to three decimal places as needed.) (c) Because the value lies the confidence interval, we the null hypothesis. (Type an integer or decimal. Do not round.) Click to select your answer(s) and then click Check Answer.
