Please answer all questions with explanations and remember to round the numbers to one decimal place.

8. I am interested in knowing about the relationship between age and reading. I have sampled 10 people and asked them their ages and how many hours they read each week. Below is a scatterplot showing the data points. (5 POINTS TOTAL FOR Q8) 30 25 20 Hours of reading per week 15 10 10 20 30 40 50 60 70 80 Age I have used statistical software to draw a "best fit" linear regression line through the data points. The line has a y-intercept of 1.5 and a slope of 0.3. a. Based on our sample findings, how many hours would we expect a 37-year old person to read each week? Show all work and report all numbers to one decimal place. (3 points) b. What makes this regression line a "best fit" for these data points? Write a couple of sentences describing the ways in which it is superior to other lines that could be drawn. Be as specific as you can. (2 points)
