Asked Oct 31, 2019

From a sample with n=32, the mean number of televisions per household is 4 with a standard deviation of 1 television. Using Chebychev's theorem, determine at least how many of the households have between 2 and 6 televisions.

Step 1

Chebyshev’s rule can be used for the large set data. It says that at least 1-1/*k*^{2} percentage of the data falls within the *k* standard deviation of the mean, where *k* is a positive number greater than 1. It can be represented as:

Step 2

According to the provided data, for a sample size, *n* is 32, the mean, µ is 4 with a standard deviation, σ of 1.

The number of standard deviations under which the values 2 and 6 are falling can be obtained by calculating the *z*-score.

Step 3

Using Chebyshev’s Inequality, the percenta...
