cognitive function in centenarians. A geriatric researcher looked at the effect of AGE (years), EDUCATION level (years of schooling), and SEX(0=female, 1=male) on cognitive function in 162 centenarians. Cognitive function was measured using standardized psychometric and mental functioning tests with higher scores corresponding to better cognitive ability. Using these data, a multiple regression computer run delivered the following multiple regression model:

y=99.4+(0.165).AGE+0.522.EDUCATION+1.112.SEX

a)Based on this model, describe the effect of AGE on cognition scores in centenarians.

b)Based on this model, describe the effect on EDUCATION on cognition scores in centenarians.

c) Based on this model, describe the effect of SEX on cognition scores in centenarians.

d) using information from this model, predict the cognition score of:

A man who is 100 years old and completed 12 years of education.
