Researchers wish to determine if a relationship exists between age and systolic blood pressure (SBP)

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) 35      37   42   46   53   57   61   65   69   74

SBP(y) 102  127  120  131 126 137 140 130 148 147

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.
