A sample is chosen randomly from a population that can be described by a Normal model. Complete parts a and b below. a) What's the sampling distribution model for the sample mean? Describe shape, center, and spread. Choose the correct answer below. A. Normal, with a center at σnand a standard deviation of μ. B. Normal, with a center at μand a standard deviation of σn. C. Normal, with a center at σand a standard deviation of μn. D. Normal, with a center at μnand a standard deviation of σ. Part 2 b) If a larger sample is chosen, what's the effect on this sampling distribution model? A. The standard deviation will be smaller, but the center will remain the same. B. The center will be smaller, but the standard deviation will remain the same. C. The center will be larger, but the standard deviation will remain the same. D. The standard deviation will be larger, but the center will remain the same.
