Here are the average global temperatures for the contiguous united states over the last 30 years (measured in of). use the table in the image below to answer the 5 questions that come with it.
1. statistical regression can be sensitive to relatively large numbers. to simplify these numbers, recode each year so that 1985 is coded as year 1 and 2014 is coded as year 30.
2. on a separate page, make a time plot of this data (horizontal axis = coded year,
vertical axis = average temperature). do not connect the dots.
3. using technology, find the regression line that best fits this data. report your result in the form
average temp = + (coded year)
4. what average temperature does your regression equation predict for the year 1997?
5. what was the actual average temperature in the year 1997?

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
