Regression Analysis: peak heart rate versus age

The regression equation is

peak heart rate = 222 - 1.14 age

Predictor CoefSE Coef T P

Constant 222.271 6.025 36.89 0.000

age -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".

H_o: = 0 (no linear relationship)

H_a: 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.
