You are conducting a survey on the number of people per house in your region. From a sample with n = 60, the mean number of people per house is 3 and the standard deviation is 1 person. Using Chebychev’s Theorem, determine at least how many of the households have 0 to 6 people.

Chebychev's Theorem The portion of any data set lying within k standard deviations (k > 1) of the mean is at least 1 k = 2: In any data set, at least 1 2 standard deviations of the mean. k = 3: In any data set, at least 1 12 == = or 75%, of the data lie within 1 32 == 8 lie within 3 standard deviations of the mean. or about 88.9%, of the data
