Show transcribed image text An electric utility has placed special meters on 10 houses in a subdivision that measures the energy consumed (demand) in an hour. The company believes that the true population mean is 20 kw. What is the probability that average energy consumed in an hour from this sample of houses is less than 19.5 kw? a) Define the random variable in words. b) Is the random variable discrete or continuous? How can you tell? c) Does the random variable have a specific probability distribution with a name? . If so, what is it? What are the numerical values of necessary parameters? What is/are the relevant equations or calculator functions needed to solve this problem? If not, what will have to be derived in order to solve the problem? ·
