You can put this solution on YOUR website! From a random sample of households, the number of television sets are listed. Find the sample mean and standard deviation of the data.
Number of televisions 0 1 2 3 4 5
Number of households 1 8 13 10 5 3
----------------------------------------
Multiply each # of tv's by its corresponding # of households = 99
Divide by the # of households to get the mean # of tv's = 2.475
----------
mean = 2.475
std = 1.2401
=================
I used a TI-84 to get the std.
Enter data into L1,L2
Select STAT; CALC; 1-Var Stats L1,L2 ; ENTER
