Q3.8 To conserve oxygen, the heart rate of penguins slows when they dive. For 23 Emperor penguins, researchers have measured the dive heart rate (bpm) and the duration of the dive (minutes) for each penguin. The researchers want to further explore a possible relationship between dive duration and heart rate to predict heart rate from the length of a penguin's dive. Below are the data for each penguin: duration 2.80 1.00 1.50 2.00 0.50 3.00 3.20 4.00 4.10 4.88 5.10 5.30 6.30 5.98 8.10 8.12 12.10 9.70 10.50 11.20 10.90 13.00 9.10 heart rate 88 110 109 85 108 90 92 88 85 70 65 68 62 46 42 35 28 32 30 31. 34 22 38 Use SPSS or other technology to produce the output necessary to answer the following questions. a) Produce a scatterplot and use it to describe the apparent relationship between the dive duration and dive heart rate. b) State the regression equation. c) Is it meaningful to interpret the y-intercept for this study? Explain. d) Predict the heart rate of a penguin that dives for 16 minutes. Is this prediction reliable? Explain. Q3.8 To conserve oxygen, the heart rate of penguins slows when they dive.
