A customer service department asks its customers to rate their over - the - phone service on a scale of 1 - 2 0 immediately after their service has been completed. The department then matches each customer's rating with the number of minutes the person waited on hold. The accompanying table shows the ratings and number of minutes on hold for 1 0 randomly selected customers. Use this information to complete parts a through e . Minutes Rating 4 1 4 8 1 3 0 1 8 4 9 5 1 4 1 1 6 1 0 1 5 2 1 9 7 1 3 3 1 3 a . Construct a scatter plot for these data. Choose the correct graph below. A . 0 1 2 5 2 1 Minutes Rating A coordinate system has a horizontal axis labeled Minutes from 0 to 1 2 in increments of 1 and a vertical axis labeled Rating from 5 to 2 1 in increments of 1 . Points are plotted as follows: ( 4 , 1 4 ) ; ( 8 , 1 3 ) ; ( 0 , 1 8 ) ; ( 4 , 9 ) ; ( 5 , 1 4 ) ; ( 1 , 1 6 ) ; ( 1 0 , 1 5 ) ; ( 2 , 1 9 ) ; ( 7 , 1 3 ) ; ( 3 , 1 3 ) . Your answer is correct.B . 5 2 1 0 1 2 Rating Minutes A coordinate system has a horizontal axis labeled Rating from 5 to 2 1 in increments of 1 and a vertical axis labeled Minutes from 0 to 1 2 in increments of 1 .

Calculate the slope and y - intercept for the regression equation. The slope is b Subscript 1 equals negative 0 . 3 7 2 . ( Round to three decimal places as needed. ) Part 3 The y - intercept is b Subscript 0 equals select: 1 6 . 0 3 7 1 6 . 0 3 7 . ( Round to three decimal places as needed. ) Part 4 c . Provide an interpretation for the value of the slope. Because the slope is negative , it can be concluded that an increase of one in the hold time will decrease the rating by an average of select: 0 . 3 7 2 0 . 3 7 2 .
