Researchers wish to determine if a relationship exists between age and systolic blood pressure (SBP). The accompanying table gives the age and systolic blood pressure for 10 adults.

Age(x)35374246535761656974

SBP(y)102127120131126137 140130148147

a. Find a linear model for these data using age (x) to predict systolic blood pressure.

b. Use the results from part (a) to predict the systolic blood pressure for a person who is 42 years-old, 53-years-old, and 69-years-old. How well do the actual data agree with the predicted values?

c. Use the results from part (a) to predict the systolic blood pressure for a person years-old and 70-years who is 45- -old.

2.Administering a standard intelligence quotient (IQ) test, we expect about one-third of the scores to be more than 12 units above 100 or more than 12 units When below 100. Describe this situation by writing an absolute value inequality.
