Question

You measure the volume of 50 bottles of water, and calculate the average of these volumes. Suppose that the population of all bottles from which you are sampling has population mean mu = 300 and standard deviation sigma = 5. Then the sample average y has distribution: The time in seconds between roughs heard during a lecture. Population mean and standard deviation are mu m 20.sigma - 20 You roll a six-sided die until the first time you get a 2. The random variable b the total number of rolls (including the "2").

Explanation / Answer

A. iv) Normal ( mean = 300, 0.707)

B. ii) Poisson ( lamda = 1/20 )

C. ii) Binomial ( n = 6, p = 1/6 )
