We recorded the pre-statistics course grade (in percent) and introductory statistics course grade (in percent) for 60 community college students. The standard error se for the linear regression model that predicts introductory statistics course grades using pre-statistics course grades (predicted introductory statistics course grade = -0.147 + 0.9810 (pre-statistics grade)) is about 4.5%. In terms of estimating introductory statistics course grades, what does this mean?
