Imagine a regression line that relates y = average systolic blood pressure to x = age. The average blood pressure for people 25 years old is 110, while for those 60 years old the average is 130. (a) What is the slope of the regression line? (Round the answer to one decimal place.) (b) What is the estimated average systolic blood pressure for people who are 55 years old? (Round the answer to the nearest whole number.)
