Question
I can get to the answers on excel but i don't know how to plug them in. please help Systolic Blood Pressure Agein years Weight in pounds Directions:
Data on blood pressure, age and weight were collected on 11 patients at a local walk-in clinic.
Systolic blood pressure is the maximum pressure your heart exerts while beating. (Diastolic pressure is the pressure in your veins between beats).
Using Systolic pressure as the dependent variable, perform a regression analysis on the data to the left, then answer the questions shown below. Type your response in the box below the question. Put your regression output in the area below,
