Please Type or WRITE VERY Legibly. NO Script. I need to check my work. Ignore the circled answer for part b) That was done by mistake. Again please, no script, and write with legible penmanship if you are not typing.

Statistics Question- Correlation Coefficient, Equation of Least Square Line,

The data below was collected from manufacturer advertisements listing the horsepower of their vehicles and corresponding highway gas mileage (in miles per gallon). Use this data to answer the following question.

0 Question 1 v The data below was collected from manufacturer advertisements listing the horsepower of their vehicles and corresponding highway gas mileage (in miles per gallon}. Use this data to answer the following questions. Emm- Gasmileagefy) 32.4 27.3 17.7 11.5 35.1 42.9 {a} Calculate the correlation coefficient. Round your final answer to four decimal places as needed. T=l l {b} What does the correlation coefficient tell us about the data in terms of this problem? C1 Horsepower and gas mileage are moderately correlated O Horesepower and gas mileage have almost no correlation .Horsepower and gas mileage have a strong positive correlation 0 Horsepower and gas mileage have a strong negative correlation {c} Write the equation of the least squares line. Round all numbers to four decimal places as needed. {d} Interpret the slope of the least squares line in terms of this problem. O The rate of change in highway gas mileage is increasing 0 The rate of change in horsepower is decreasing C3 The rate of change in horsepower is increasing C3 The rate of change in highway gas mileage is decreasing {e} Use the rounded version of the least squares line from part (c) to determine the horsepower of a vehicle that gets 25 highway miles per gallon. Round your answer to the nearest integer as needed
