<PRE><B>Question 477046</B>
Household income does not tend to follow a normal distribution in a particular state, yet average income is approximately $45,000/year in this state, with a standard deviation of about $9,000. Within what income range would approximately 93.75% of the household incomes lie within this state? Show all work as to how this is obtained. ......
-----
According to Chebychev about 95% of data lies within 2 standard deviations
of the mean of the data.
----
Lower limit: 45000-2*9000 = $27000
Upper limit: 45000+2*9000 = $63000
