A frequency distribution is shown below. Complete parts? (a)through? (e). The number of dogs per household in a small town.
?(a) Use the frequency distribution to construct a probabilitydistribution. ?(b) Find the mean of the probability distribution.?(c) Find the variance of the probabilitydistribution. (d) Find the standard deviation of theprobability distribution. ?(e) Using the found values of the meanand the standard? deviation, an interpretation of the results inthe context of the? real-life situation is that a household onaverage has _ dog with a standard deviation of _ dog.
Dogs x=0 1 2 3 4 5
