Answer:At least

9households have between 0 and 4 televisions.Step-by-step explanation:According to the Chebychev’s theorem,

Here

kis a constant.Given:

μ= 2σ= 1n= 12Using 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

9households have between 0 and 4 televisions.
