Question

A researcher found the average cost of one and two-bedroom apartments for different cities and graphed the data in a scatter plot, with costs of one-bedroom apartments along the x-axis. The variables have a strong linear correlation and the equation for the regression line is yˆ=1.377x+137.763 .
Based on the equation, what should the researcher expect for the average cost of a two-bedroom apartment in a city where the average cost of a one-bedroom apartment is $724?


about $1272


about $1135


about $1083


about $1062

Answer 1

The average cost of a two-bedroom apartment in the city will be about $1135

Step-by-step explanation:

The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.

Given that the average cost of one-bedroom apartment is $724, then using this value for x

yˆ=1.377*724+137.763  = 1134.711

This value is approximately $ 1135
