Question: A study was conducted to determine if there was a linear relationship between a person's age and their peak heart-rate. Data were collected from 8 people and are listed below.

Age(x) 15 25 30 35 40 50 45 20
Peak Heart Rate (y) 220 190 180 170 170 160 170 200

Do a complete regression analysis using the following steps:

Draw the scatter plot

Compute the value of the correlation coefficient

Test the significance of the correlation coefficient at = 0.01, using Table 1 (located at the end of the paper)

Determine the regression line equation.

Plot the regression line on the scatter plot.

Predict y’ for a specific value of x.

Use your regression line model to predict the peak heart rate of a 32-year-old person.
