Output from multiple regression appears below. The automobile executive also had a hypothesis about price. For that hypothesis, the computed P-value was 0.038. At the α{“version”:”1.1″,”math”:”α”}=0.05 significance level, what is the conclusion about the automobile executive’s hypothesis about price? Coefficients Standard Error t Stat P-value Lower 95% Upper 95% Intercept 494.234 89.618 5.515 0.000 305.156 683.311 Price 0.857 1.149 0.746 0.466 -1.567 3.282 Range 0.603 0.279 2.163 0.045 0.015 1.191 FuelEconomy 0.160 0.675 0.237 0.816 -1.264 1.584

The next seven questions are about a dataset related to owner satisfaction with electric cars and trucks. Owners of 21 models of car were surveyed by J.D. Power. For each model of car, average owner satisfaction was recorded on a scale from 500 to 1000 points. There are three potential explanatory variables: Price, measured in thousands of dollars (so $50,000 would be recorded as 50 in the model) Range, measured in miles FuelEconomy, measured in MPGe (miles per gallon equivalent) The correlation matrix of explanatory variables appears below. What is the interpretation of the correlation between range and fuel economy? Price Range FuelEconomy Price 1 Range 0.527 1 FuelEconomy -0.687 0.001 1
