Problem
For the following pair of variables state the units that might be used to measure each variable. then state whether you believe that the two variables are correlated .if you believe they are correlated, state whether the correlation is positive or negative. explain your reasoningTo measure fertility rate for women the unit _ might be used. to measure life expectancy the unit _ might be used. what correlation if any is there between the variables?
Solution
To measure fertility rate for women the number of births per 1000 women might be used.
To measure life expectancy the years might be used.
what correlation if any is there between the variables?
For this case we would expect that the correlation would be positive. With higher number of life expectancy years we would expect a higher number of births
