Question: Consider the linear regression model y = 675.30 - 5.87x with = 7.32. which relates the viscosity y of a substance to the temperature

Consider the linear regression model
y = 675.30 - 5.87x
with σ = 7.32. which relates the viscosity y of a substance to the temperature x. If a sample of the substance is prepared at temperature 80, what is the probability that its viscosity is less than 220?
