Best ResponseYou've already chosen the best response.02. Use the regression equation from the previous problem (with constants rounded to three decimal places) to estimate the percentage of households in the United States that had a dog for a pet in 1989 and in 1999. Round the answers to one decimal place. Do not include a percent sign. For 1989 I got 37.7 as my answer For 1999 I got 29.7 as my answer I’m not sure if my answers are correct and I know if the equation is not right then the other answers will be wrong.

Best ResponseYou've already chosen the best response.0yeah check the years again. Should be y = 0.8022x + 42.215

Best ResponseYou've already chosen the best response.0Ok I see I was probably thinking at the time to put the year for 0.8022 would be 0.802 to be three decimal places. Then do I just plug in 1989 and 1999 into that formula?

Best ResponseYou've already chosen the best response.0But for 1989 and 1999 I used the y=.802x+1632.889 formula?

Best ResponseYou've already chosen the best response.0when you plugged in 1989 and 1999 into the "wrong" formula it worked because that formula used years. To use the "right" formula you'd have to change them to 6 and 16 respectively. It will give you the same result

Best ResponseYou've already chosen the best response.0Oh so I will still get 37.7 for 1989 and 29.7 for 1999?

Best ResponseYou've already chosen the best response.0@peachpi one more question, I plugged in 6 into 0.802(6) + 42.215 and got 37.4 and 0.802(16) + 42.215 and got 29.38 or 29.4 which I think may be the answers because I got 37.7 and 29.7 wrong. Also where does the 6 and 16 come from?

Best ResponseYou've already chosen the best response.0Yeah it is 37.4 for 1989 and 29.4 for 1999, I had my rounding on to the whole using years since 1983, so 1989  1983 = 6 1999  1999 = 16

Best ResponseYou've already chosen the best response.0Would that also be for the formula to y=0.802x + 42.213 instead of .215?
