Hi. I need help solving linear correlation coefficient , test statistics, and p-value. Please help
Transcribed Image Text:Listed below are annual data for various years. The data are the numbers of cars sold (thousands) and the numbers of points scored in the Super Bowl. Construct
a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using a = 0.05. Is there sufficient evidence to conclude that there is a linear
correlation between those two variables? Would it be reasonable to expect a correlation?

Because the P-value is greater than the significance level 0.05, there is not sufficient evidence to support the claim that there is a linear correlation between car
sales and Super Bowl points for a significance level of α = 0.05.
Based on the results, would it be reasonable to expect a correlation?
