Most chickens reach maturity and begin laying eggs at around 20 weeks of age. From this point forward, however, as the chicken ages,its eges its egg production decreases. A farmer was given a flock of 100 chickens (all of which were the same age) and asked to meaure daily egg output for the entire flock at random intervals starting at maturity until the chickens were 70 weeks old. The data are recorded in the scatteplot below and the line of best fit has been drawn.

Based on the line of bast fit, what is the predicted number of eggs that will be produced by the flock when it is 33 weeks past maturity ?

Options

A. 33
B. 50
C. 58
D. 64

Answer

C

Explanation

In this case, you merely need to match the y-value on the line of best fit with the x-value of 33, since the x-axis of the graph represents the number of weeks after maturity. Take carer to use the line of best fit rather than an individual point on the graph, (B) is a trap answer. At `x = 33,` the y-value of the line of best fit seems to be just shy of 60. Thus, (C ) is correct.
