Suppose a simple random sample of size n = 10 is obtained from a population with u = 65 and o = 19. (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? Assun the normal model can be used, describe the sampling distribution x. (b) Assuming the normal model can be used, determine P(x < 68.9). (c) Assuming the normal model can be used, determine P(x 2 67.3). 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? O A. There are no requirements on the shape of the distribution of the population. O B. Since the sample size is large enough, the population distribution does not need to be normal. O C. The population must be normally distributed and the sample size must be large. D. The population must be normally distributed. Assuming the normal model can be used, describe the sampling distribution x. Normal, with = 65 and = 19 19 B. Normal, with = 65 and V10 10 O c. Normal, with = 65 and %3D V19 (b) P(x < 68.9) = (Round to four decimal places as needed.)
