Q1) Do reading and TV viewing compete for leisure time? To determine, a communication specialist interviewed sample of 10 children regarding number of books they had read in the last year and number of hours they had spent watching TV on daily basis. Researcher was nice sufficient to give you following information:

i) Use alpha level. 05 to compute and interpret Pearson's r and to test whether it is important (using all your steps for hypothesis test).

ii) Use alpha level .05 to compute and interpret constant and slope and to test whether it is important (go through all of your steps of hypothesis testing). Standard error of b is .015.
