Fit a line to these data where the november snowfall is the independent variable and the december – may snowfall is the dependent variable. make a plot that superimposes this linear fit over the data pairs. based on the least squares fit of the line to these data pairs, could you use this tv weatherman’s rule to accurately forecast twin cities’ snowfall in the dec. – may period based on snowfall during the previous november’s snowfall?

At the "no mutants allowed" country farm, every sheep has 4 legs, every chicken has two legs, and all animals have only 1 head. asked to count how many sheep and chicken are in the fields, a farm boy reports back that there are 140 feet and 50 heads. how many sheep and chicken are there? there are sheep and chicken at the farm.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
