a. Is there an association between the practice midterm grade and the midterm grade of a student? If yes is it positive or negative? There appears to be a positive association between the two variables. Part 2 of b. Use technology to find the equation of the line of best fit, y = mx + b, and the coefficient of determination and interpret the slope, the vertical intercept, and the coefficient of determination. (Round the answers to 3 decimal places.) i. m = 1.527 01.526 percents/point o is the the change of midterm grade per 1 unit of change in practice midterm grade ii. b-43.7 -43.740 percents O is the the midterm grade when the practice midterm grade is zero iii.r = 0.850 0.850 hence there is a strong o linear relation. Part 3 of c. Use the line of best fit to: i. estimate the midterm grade of a student whose practice midterm grade is 94 points. Answer: percents (Round the answer to the nearest unit.) ii. estimate the practice midterm grade of student whose midterm grade is 84 percents. Answer: points (Round the answer to the nearest unit.) b. Use technology to find the equation of the line of best fit, y = mx + b, and the coefficient of determination and interpret the slope, the vertical intercept, and the coefficient of determination. (Round the answers to 3 decimal places.) i. m 4.290 0 4.290 10 dollars/sq. foot is the the change of price per 1 unit of change in square footage ii. b = == 291.5 291.506 1000 dollars the price when the square footage is zero iii.r = = 0.874 0.874 hence there is a strong O is the c. Use the line of best fit to: i. estimate the price of a home whose square footage is 1900 sq. feet. Answer: linear relation. Part 3 of 3 dollars (Round the answer to the nearest unit.) ii. estimate the square footage of home for sale whose price is 367000 dollars. Answer: sq. feet (Round the answer to the nearest unit.) b. Use technology to find the equation of the line of best fit, y = mx + b, and the coefficient of determination and interpret the slope, the vertical intercept, and the coefficient of determination. (Round the answers to 3 decimal places.) i. m = 1.173 1.172 dollars/page the change of price per 1 unit of change in page count ii. b = -25.5 -25.585 dollars the price when the page count is zero iii. = 0.898 0.899 hence there is a strong O is the is the c. Use the line of best fit to: i. estimate the price of a college textbook whose page count is 95 pages. Answer: linear relation. Part 3 of 3 dollars (Round the answer to the nearest unit.) ii. estimate the page count of textbook whose price is 54 dollars. Answer: pages (Round the answer to the nearest unit.)
