A recent study1 examined several variables on collegiate football players, including the variable Years, which is number of years playing football, and the variable Percentile, which gives percentile on a cognitive reaction test. The regression line for predicting Percentle from Years is: Percentile = 102-3.34-years. Predict the cognitive percentile for someone who has played football for 8 years and for someone who has played football for 13 years.

Answer:

Step-by-step explanation:

rth percentile = r(n + 1)/100 (where n = 7)

i) For someone who had played football for 8 years = 8(7 + 1)/100 = 8*8/100 = 64/100

ii) For someone who had played football for 13 years = 13(7 + 1)/100 = 13*8/100 = 104/100
