Friday

After we took the make-up regression quiz, I assigned this problem:

1978—63,042

1979—226,260

1980—907,075

1981—2,826,095

Year vs. acres devastated by the gypsy moth.

 

Please do this:

1)       Graph and describe

2)       Take log(acre) to linearize

3)       Graph and describe year vs. log(acre)

4)       Find LSRL, write it down in context.

5)       Graph resid and interpret

6)       Make a prediction for 1982
