The yeаrly dаtа have been published shоwing the number оf releases fоr each of the commercial movie studios and the gross receipts for those studios. Can it be concluded that there is a linear correlation between the number of releases and the gross receipts? Results Table Number of releases 361 270 306 22 35 10 8 12 21 Gross receipts(in millions) 3844 1962 1371 1064 334 241 188 154 125 State the Null and alternate hypotheses symbolically. Find the linear correlation coefficient Find the P-value State the decision State the conclusion If a linear correlation exists, find the regression equation. If no correlation exists, state that the regression equation is not a good model for the data. Find the best predicted gross receipts for 200 new releases.
