A particular article used a multiple regression model to relate y-yield of hops to x₂ - mean temperature (°C) between date of coming into hop and date of picking and x₂ - mean percentage of sunshine during the same period. The model equation proposed is the following. y=415.11-6.6r₁ -4.50r₂+c (a) Suppose that this equation does indeed describe the true relationship. What mean yield corresponds to a temperature of 20 and a sunshine percentage of 39? (b) What is the mean yield when the mean temperature and percentage of sunshine are 19.1 and 42, respectively?

![A particular article used a multiple regression model to relate y = yield of hops to x₁ = mean temperature (°C) between date of coming into hop and date of picking and x₂ = mean percentage of sunshine during the same period. The model equation proposed is the following.
y = 415.116.6x₁4.50x2+e
(a) Suppose that this equation does indeed describe the true relationship. What mean yield corresponds to a temperature of 20 and a sunshine percentage of 39?
(b) What is the mean yield when the mean temperature and percentage of sunshine are 19.1 and 42, respectively?
