Question: A study was conducted to determine whether a correlation exists between consumer’s perceptions on TV commercial (measured on special scale) and their interest in purchasing the product (measured on a scale). The results are \[n=65,\text{ }r=0.37.\] is there statistical evidence (at 0.05 level of significance) of a linear correlation between the two variables?
