Complete question:

A recent study 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 Percentile from Years is:

Percentile 102 - 3.34 Years.

(a) Predict the cognitive percentile for someone who has played football for 7 years and for someone who has played football for 16 years. Enter the exact answers. The cognitive percentile for someone who has played football for 7 years is The cognitive percentile for someone who has played football for 16 years is

i) Cognitive percentile for someone who has played football for 7 years is 76.62

ii) Cognitive percentile for someone who has played football for 7 years is 46.56

Step-by-step explanation:

Given the regression equation: 102 - 3.34 (years)

Required:

Predict the cognitive percentile for someone who has played football for 7 years and for someone who has played football for 16 years

a) Cognitive percentile for someone who has played football for 7 years:

102 - 3.34 (years)

= 102 - 3.34(Y)

Substitute 7 for Y

102 - 3.34(7)

= 102 - 23.38

= 76.62

Cognitive percentile for someone who has played football for 7 years is 76.62

b) Cognitive percentile for someone who has played football for 16 years:

102 - 3.34 (years)

= 102 - 3.34(Y)

Substitute 7 for Y

102 - 3.34(16)

= 102 - 53.44

= 46.56

Cognitive percentile for someone who has played football for 7 years is 46.56

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )
