An object is thrown from the top of a building. The following data measure the height of the object from the ground for a five second period. Calculate the correlation coefficient using technology (you can copy and paste the data into Excel). Round answer to 4 decimal places.
Make sure you put the 0 in front of the decimal.
Seconds | Height |
0.5 | 111.75 |
1 | 110.875 |
1.5 | 105.18 |
2 | 100.275 |
2.5 | 91.3 |
3 | 79.875 |
3.5 | 71.083 |
4 | 57.83 |
4.5 | 32.65 |
5 | 0 |

Question 13 (1 point)
Bone mineral density and cola consumption has been recorded for a sample of patients. Let x represent the number of colas consumed per week and y the bone mineral density in grams per cubic centimeter. Assume the data is normally distributed.
Cola Consumed | Bone Mineral Density (g) |
1 | 0.8777 |
2 | 0.8925 |
3 | 0.8898 |
4 | 0.8769 |
5 | 0.8999 |
6 | 0.8634 |
7 | 0.8762 |
8 | 0.8888 |
9 | 0.8552 |
10 | 0.8546 |
11 | 0.8762 |
Based on your results, If the Colas Consumed increases by 1, Bone Mineral Density, on average, decreases by approximately how much? Round to 3 decimal places. Make sure you put a 0 in front of the decimal.
