Question

13. the scatterplot shows the number of hours of sleep needed per day by age, based on the scatterplot what is the best prediction of the average number of hours of sleep for a 16 year old person?​

Answer 1

Answer:

Best prediction is 8.5 hours.

Step-by-step explanation:

Since there is no samples for the age of 16 years, the best estimate (prediction) would be to interpolate: compute the average between values of the neighboring ages, namely 8 and 9 (approximately). The closest choice to an average like that is 8.5 hours.
