The scatterplot below shows the average weekly temperature and pints of ice cream consumed per person at an ice cream shop. There are two lines one of which is the least squares line. The equation of the least squares line is y = .2069 + .0031x where x = temperature and y = pints of ice cream. Which is the least squares line? orange line (top line) blue line (bottom line) Predict the pints of ice cream consumed when the temperature is 70. Select the option closest to the correct value. 0.42 0.45 0.50 The spreadsheet \"Shoe size versus height\" has the shoe sizes and heights of 24 college-age males. We wish to predict height (y) from shoe size (x). What is the slope of the regression line? Use spreadsheet functions to compute it. Round your answer to two decimals. One of the individuals whose shoe size is 11 has a height of 75. Use the graph that is shown with the data set on the spreadsheet to find the error of prediction. Select the answer closest to the correct value. -2.5 -0.5 0.5 2.5

Solution

Blue line

y(70) = 0.4239

Hence option a
