Milk utilization 2020. In September 2020, the past two years’ statistics from the monthly survey of milk availability and usage by dairies in England and Wales was retrieved to create the Usage of Milk by Dairies in the United Kingdom ( June 2019) release. A linear model predicting the relationship between the amount of yogurt produced

(thousand tons) and the amount of milk (million liters)

sold to dairy companies in the United Kingdom is:

ProdYogurt = 1056.869 + 5.483 Amound of milk

a) What is the explanatory variable?

b) What is the response variable?

c) What does the slope mean in this context?

d) What does the y-intercept mean in this context? Is it meaningful?

e) If 1100 million liters of milk is sold to dairies in the United Kingdom, what is the predicted production of yogurt?

f) Suppose the predicted amount of yogurt produced is 7500 thousand tons with 1150 million liters of milk sold to dairies in the United Kingdom. Is this reliable g) What is the residual for part f ?
h) The residual standard deviation is 63.856 thousand tons.
What does that tell you about the likely practical use of this model for predicting the amount of yogurt produced?
