A power company located in southern Alabama wants to predict the peak power load (i. e., the maximum amount of power that must be generated each day to meet demand) as a function of the daily high temperature (X). A random sample of summer days is chosen, and the peak power load and the high temperature are recorded each day. The file P10_40.xlsx contains these observations. A. Create a scatterplot for these data. Comment on the observed relationship between Y and X. B. Estimate an appropriate regression equation to predict the peak power load for this power company. Interpret the estimated regression coefficients. C. Analyze the estimated equation’s residuals. Do they suggest that the regression equation is adequate? If not, return to part b and revise your equation. Continue to revise the equation until the results are satisfactory. D. Use your final equation to predict the peak power load on a summer day with a high temperature of 100 degrees.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
