A survey was conducted of 118 households in a neighborhood, asking how many pets each home had. The survey results are tabulated below.
l8 Suppose melee households in the above survey are the entire population of households under consideration. The frequency table then shows the distribution of possible values for the number of pets in a randomly chosen household. The population variance for a discrete variable is given by the following equation: Var(X) = 2:1(Xi x)2P[X = Kg] This is a \"weighted average" of the squared deviations. We can modify this to t our current problem: fr 1: mm = Lots mg ( iii. ') What is Var(X) for the above distribution? Note that the population mean px required here will be the same as the sample mean X you should have used for Question 08. Please enter your response rounded to 2 decimal placesStep by Step Solution
