Two variables have a positive linear correlation. Is the slope of the regression line for the variables positive or negative?
Can that regression be used to estimate the effect of the national unemployment rate on an individual’s earnings? Explain.
< Prev The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, y = bo + b₁x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

A frequent flyer was interested in the relationship between dollars spent on flying and the distance flown. She sampled 20 frequent flyers of a certain airline. She collected the number of miles flown in the previous year and the total amount of money the flyer spent. A regression line of distance flown on money spent was fit to the data: y^=24000+10x. One person in the sample spent $3000 and flew 42,567 miles. What would be the residual (or error) in the predicted distance this person would fly?
