The accompanying technology output was obtained by using the paired data consisting of foot lengths (cm) and heights (cm) of a sample of 40 people. Along with the paired sample data, the technology was also given a foot length of 15.2 cm to be used for predicting height. The technology found that there is a linear correlation between height and foot length. If someone has a foot length of 15.2 cm, what is the single value that is the best predicted height for that person?

Mathew Armstrong · Answer 1

76 inches

Step-by-step explanation:

It should be understood that 15.2cm is equal to 5 inches.

Since the height = 5 * size of the foot

= 5 * 15.2 = 76

Therefore, a person with 15.2cm as the size of the foot will have the height of 76 inches.
