For samples of the specified size from the population described, find the mean and standard deviation of the sample mean x. The National Weather Service keeps records of snowfall in mountain ranges. Records indicate that in a certain range, the annual snowfall has a mean of 86 inches and a standard deviation of 14 inches. Suppose the snowfalls are sampled during randomly picked years. For samples of size 49, determine the mean and standard deviation of x. A) μ x = 86; σ x = 2 B) μ x = 2; σ x = 86 C) μ x = 14; σ x = 86 D) μ x = 86; σ x = 14

27. For a chain nuclear fission of U$^{235}$ the moderation of neutron is a must because very high energy neutron: (1) will collide inelastically with the nucleus and so there is no fission (2) will collide elastically with the nucleus and so there is no fission (3) will be trapped in the nucleus and hence no fission (4) repelled by nucleus
