Use the data to the right on the minutes a certain actor spent shirtless in movies to complete parts (a) through (c) below. a. Determine the correlation coefficient, rounded to two decimal places, between the minutes the actor appeared shirtless in a film and the film's opening weekend gross. r= (Do not round until the final answer. Then round to two decimal places as needed.) b. Find the equation of the regression line for the minutes the actor appeared shirtless in a film and the film's opening weekend gross. y=x+1 (Round to two decimal places as needed.) c. What opening weekend gross can we anticipate in a film in which this actor appears shirtless for 20 minutes? The anticipated opening weekend gross will be about $ million dollars. (Round to one decimal place as needed.) n which scatter plot is r=0.7 ? (B) (C) (E) (F) The graph I shows a scatter plot with a correlation coefficient of r=0.7. (Type A, B, C, D, E, or F.) The results of a certain medical test are normally distributed with a mean of 121 and a standard deviation of 18 . (A score above 133 is considered unhealthy). Use the given table to find the percentage of people with readings below 130. The percentage of people with readings below 130 is %. (Round the final answer to the nearest hundredth as needed. Round the z-score to the nearest tenth as needed.) Use the table below to find the percentage of data items in a normal distribution that lie between z=0.2 and z=1.5. The percentage of data items in a normal distribution that lie between z=0.2 and z=1.5 is %
