City Hall wishes to learn about the rate of parking mater use. They choose 8 Downton blocks at random and on each block they choose 5 meters at random. Six weeks are chosen randomly from the year, and the usage on each meter is measured everyday for all the meters in those weeks.Write out an appropriate linear model
The electric power consumed each month by a chemical plant is thought to be related to the average ambient temperature (x₁), the
number of days in the month (x₂), the average product purity (x3), and the tons of product produced (x4). The past year's historical data
are available and are presented in the following table:

You have run an ANCOVA model that predicts fuel efficiency (in miles per gallon) as a function of vehicle weight (measured in thousands of lbs, where a value of 2.5 would correspond to 2,500 lbs), horsepower, and number of cylinders in the car (cylinders is a factor in this model with 3 levels: 4 cylinders, 6 cylinders, and 8 cylinders). Your analysis tells you the following; The mean miles per gallon of all cars analyzed is 20.09 The mean weight of all cars analyzed is 3.217 thousand lbs The mean horsepower of all cars analyzed is 146.7 The regression coefficient for weight is -3.18 miles per gallon per additional thousand lbs The regression coefficient for horsepower is -0.023 miles per gallon per additional unit of horsepower Cars with 4 cylinders get 2.13 more miles per gallon, on average, than the average car Toyota is…arrow_forwardThe following table shows economic development measured in per capita income, PCINC. a.
