The null and alternative hypotheses for correlation are:H0:H0: ? ρ r μ == 0 H1:H1: ? μ ρ r ≠≠ 0 The p-value is: Round to 4 decimal places. Use a level of significance of α=0.05α=0.05 to state the conclusion of the hypothesis test in the context of the study. There is statistically insignificant evidence to conclude that there is a correlation between the number of movies watched per year and the number of books read per year. Thus, the use of the regression line is not appropriate. There is statistically significant evidence to conclude that a person who watches fewer movies will read fewer books than a person who watches fewer…
