You are interested in the relationship between watching reality T.V. and headaches. Consider the following data relating to hours spent watching reality T.V. (X) and average number of headaches (Y).

g. Compute the Pearson correlation (r)

h. What proportion of variability in Y scores can be predicted from the relationship with X? (hint: remember the coefficient of determination)

i. Based on your results, would we reject or fail to reject the null hypothesis about a relationship between these two variables (two-tailed, α= 0.05)?

j. From these observations, can we conclude that hours spent watching reality T.V.causedincreases in headaches? Why or why not?
