Can movie rental revenue be predicted? A movie studio wishes to determine the relationship between the revenue from rental of comedies on streaming services and the revenue generated from the theatrical release of such movies. The studio has the following bivariate data from a sample of fifteen comedies released over the past five years. These data give the revenue x  from theatrical release (in millions of dollars) and the revenue  y  from streaming service rentals (in millions of dollars) for each of the fifteen movies. Also shown are the scatter plot and the least-squares regression line for the data. The equation for this line is  =y+3.620.15x .   Theater revenue, x (in millions of dollars) Rental revenue, y (in millions of dollars) 60.9 9.5 19.9 5.0 25.4 7.0 25.8 9.1 14.4 1.6 30.7 5.3 49.0 16.5 27.6 11.6 27.4 3.0 12.9 10.6 59.7 16.2 7.1 3.6 36.5 12.3 66.2 9.9 44.5 7.3 Send data to calculator Send data to Excel        Rental revenue (in millions of dollars) y 2 4 6 8 10 12 14 16 18 x 10 20 30 40 50 60 70 0                                                                   Theater revenue (in millions of dollars) Based on the studio's data and the regression line, answer the following.   (a) From the regression equation, what is the predicted rental revenue (in millions of dollars) when the theater revenue is 45.6 million dollars? Round your answer to one or more decimal places.       (b) From the regression equation, what is the predicted rental revenue (in millions of dollars) when the theater revenue is 66.2 million dollars?

Overweight or obese adults from psychiatric programs were recruited and randomly assigned to a treatment group or control group. Patients in the treatment group received both weight-management sessions plus exercise sessions plus their usual care. Patients in the control group received their usual treatment for mental illness and no additional treatment. After 18 months, some of the patients had lost 5% or more of their weight, and some had not. The table summarizes the data. Complete parts (a) and (b) below. Treatment Group Control Group Lost 5% or more 46 29 Did not lose 5% or more 88 106 ..... (a) Find the percentage of each group that lost 5% or more, and compare them descriptively. That is, report both percentages, and indicate what these sample percentages suggest about the effectiveness of the treatment program. Of the treatment group,% of them lost 5% or more. (Round to one decimal place as needed.) Of the control group, % of them lost 5% or more. (Round to one decimal place as…
