From a sample with nequals12, the mean number of televisions per household is 2 with a standard deviation of 1 television. Using Chebychev's Theorem, determine at least how many of the households have between 0 and 4 televisions.

At least 9 households have between 0 and 4 televisions.

Step-by-step explanation:

According to the Chebychev's theorem,

Here k is a constant.

Given:

μ = 2

σ = 1

n = 12

Using the Chebychev's theorem determine the probability of households having between 0 and 4 televisions as follows:

This implies that at least 75% of the 12 households have between 0 and 4 televisions.

Compute 75% of n = 12 as follows:

Thus, at least 9 households have between 0 and 4 televisions.
