Question Answered step-by-step Regression Analysis: peak heart rate versus age The regression… Regression Analysis: peak heart rate versus age The regression equation ispeak heart rate = 222 – 1.14 age Predictor Coef SE Coef T PConstant 222.271 6.025 36.89 0.000age -1.1405 0.1612 -7.07 0.000 Pearson correlation “r” of age and peak heart rate = -0.929 Test the hypothesis to see if there is a linear relationship. If you reject Ho, then continue. This test is on your calculator “LinRegTTest”. Ho: ? = 0 (no linear relationship)Ha: ? ? 0 (there is a linear relationship) ? = 0.05 Table value: ________ |—————-|—————| r value from above: ________ -1 0 1 p-value from the calculator = _________ Decision: _________________ Summary: _______________________________________ Find “a” and “b” from the computer print-out:”a” (constant) ___________ “b” (age) ___________write the regression equation: ________________________ Use x=40 yrs old and x=30 yrs old to find the line for the graph and plot it.
