For samples of the specified size from the population described, find the mean and standard deviation of the sample mean x. do The National Weather Service keeps records of rainfall in valleys. Records indicate that in a certain valley, the annual rainfall has a mean of 78 inches and a standard deviation of 10 inches. Suppose the rainfalls are sampled during randomly picked years, and x is the mean amount of rain in these years. For samples of size 25, determine the mean and standard deviation of x.
