A marketing firm wished to determine whether the number of television commercials broadcast was linearly correlated with the sales of its product. The data was obtained from 10 different cities and the calcuated value of r was 0.67. Is this linear correlation coeffiecient significantly greater than zero, at alpha = 0.05?
State the alternative hypothesis: Ha: rho 0 (enter the symbol)
State the degrees of freedom:
< p-value <
State the decision ( R for reject Ho and F for fail to reject Ho)
Is there reason to believe there is a positive linear correlation between the number of t.v. commercials and the sale of this product? ( yes or no)
