6-28.

Suppose you found that the correlation between the life expectancy of citizens in a nation and the average number of TVs in households in that nation is $r=0.89$. Does that mean that watching TV helps you live longer?

Read the problem carefully, what are the two variables that are being correlated?

Does having more TVs in a household automatically mean that more TV is being watched?
