Professor Moore swims 2000 yards regularly in a vain attempt to undo middle age. Here are his times (in minutes) and his pulse rate after swimming (in beats per minute) for 23 sessions in the pool: Time 34.12 35.72 34.72 34.05 34.13 Pulse 35.72 36.17 35.57 152 124 140 152 146 128 136 144 Time 35.37 A 35.57 35.43 36.05 Pulse 34.85 148 34.70 34.75 33.93 144 136 124 148 144 140 156 Time 34.60 34.00 34.35 Pulse 35.62 35.68 136 35.28 148 35.97 148 ..... 132 124 132 139 What are the independent / dependent variables ! Make a scatter plot. 3. ) An advertising company is curious about the impact the lengths of their television advertisements have on viewers' feelings about a product. They showed advertisements of different lengths to a group of volunteers and asked the volunteers to rate how positive they felt about the product on a scale of 1 to 10. Their data is shown in the table below. Avg. product rating 6.0 7.0 5.0 3.0 2.5 Ad length (seconds) 30 45 60 7 75 90 All of the scatter plots below display the data correctly, but which one of them displays the data best? By convention, a good scatter plot uses a reasonable scale on both axes and puts the explanatory variable on the x-axis. Choose 1 answer.
