Body Temperature and Heart Rate Is there any relationship between these two variables? To find out, we randomly selected 12 people from a data set constructed by Allen Shoemaker (Journal of Statistics Education) and recorded their body temperature and heart rate.13
Person | 1 | 2 | 3 | 4 | 5 | 6 |
Temperature (degrees)
| 96.3 | 97.4 | 98.9 | 99.0 | 99.0 | 96.8 |
Heart Rate (beats per minute) | 70 | 68 | 80 | 75 | 79 | 75 |
Person | 7 | 8 | 9 | 10 | 11 | 12 |
Temperature (degrees)
| 98.4 | 98.4 | 98.8 | 98.8 | 99.2 | 99.3 |
Heart Rate (beats per minute) | 74 | 84 | 73 | 84 | 66 | 68 |
a. Find the correlation coefficient r, relating body temperature to heart rate.
b. Is there sufficient evidence to indicate that there is a correlation between these two variables? Test at the 5% level of significance.
