Suppose a simple random sample of size n = 40 is obtained from a population with μ = 68 and o = 17.(a) What must be true regarding the distribution of the population in order to use the normal model to compute probabilities regarding the sample mean? Assuming the normal model can be used,describe the sampling distribution x.(b) Assuming the normal model can be used, determine P(x <71.1).(c) Assuming the normal model can be used, determine P(x270.1).Click here to view the standard normal distribution table (page 1).Click here to view the standard normal distribution table (page 2).(a) What must be true regarding the distribution of the population?A. Since the sample size is large enough, the population distribution does notneed to be normal.OB. The population must be normally distributed.OC. The population must be normally distributed and the sample size must be large.OD. There are no requirements on the shape of the distribution of the population.Assuming the normal model can be used, describe the sampling distribution X.17√40OB.

In the year 2033, Sarai Patterson is a leading traveling nurse. Sarai is interested in reducing the mean recovery time for patients after experiencing a serious injury (assume recovery times are normally distributed). Suppose the mean recovery time is presently 8.6 months. Sarai takes a random sample of 46 patients that have experienced serious injury to participate in a new treatment program and finds the sample mean is 8.1 months and a sample standard deviation of 1.2 months. Using α = 0.05, answer the following questions. a) What is the setup for your null and alternative hypothesis? b) What is the value of the test statistic? c) What is/are the critical value(s)?
