The data in the chart below is for the distance (in cm) to the near point, the point nearest the eye at which the eye can accurately focus, at a person’s age. Use a spreadsheet application to create a linear regression model for the data in the form y = mx + b, where x is age and y is near point. Using your model, predict the near point of someone who is 80 years old. Round your answer to 1 decimal place. Age (years) Near Point (cm) 10 7.5 20 9 30 11.5 40 17.2 50 52.5 60 83.3
