Suppose a simple random sample of size n = 11 is obtained from a population with ?-66 and o=14(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? Asthe normal model can be used, describe the sampling distribution x.(b) Assuming the normal model can be used, determine P(x <69.3).(c) Assuming the normal model can be used, determine P(x ? 67.9).(a) What must be true regarding the distribution of the population?A. The population must be normally distributed.B. There are no requirements on the shape of the distribution of the populationC. The population must be normally distributed and the sample size must be largeD. Since the sample size is large enough, the population distribution does not need to be normal.
