The statistical model for simple linear regression is written as u =
u represents the mean of a Normally distributed response variable, and x represents the
explanatory variable. The parameters and , are estimated, giving the linear regression
model defined by μ = 70+10x, with standard deviation = 5. Based on this, answer
