Question:

For the Male Athlete Strength data file on the text CD, the prediction equation relating y = 1 repetition maximum bench press (1RMBP) in kilograms to x = repetitions to fatigue bench press (RTFBP) is = 117.5 + 5.86 x.
a. Find the predicted 1RMBP for a male athlete with a RTFBP of 35, which was one of the highest RTFBP values.
b. Find the predicted 1RMBP for a male athlete with an RTFBP of 0, which was the lowest RTFBP value.
c. Interpret the y -intercept. Use the slope to describe how predicted 1RMBP changes as RTFBP increases from 0 to 35.
