Question

We perform a two-tailed hypothesis test on the population correlation coefficient between moviegoers' snack spending and their age, at $\alpha = 0.05$. For this, we collect a sample of 25 moviegoers' age and snack spending and the sample correlation coefficient $r = -0.373$. a. [2pts] Specify both the null and alternative hypotheses. b. [2pts] Establish the decision rule, including the critical value. Again $\alpha = 0.05$. c. [3pts] Calculate the proper test statistic. d. [2pts] What do you conclude about the null-hypothesis? What is the mathematical reason for your decision?
