<PRE><B>Question 155820</B>
Week........... 1 2 3 4 5 6
Hours at lake...2 3 2 1 4 5
Fish caught.....5 5 4 3 6 9

Use the information regarding John’s fishing trips to perform a simple (bivariate) regression analysis. Use the hours spent as the X variable, and the number of fish caught as the Y variable.
--------------
I used a TI calculator to get the following:
---------------
Calculate r and r2, standard error of the estimate, and a confidence interval for the data. Interpret the results.
---------------------
r = 0.942837
r^2 = 0.888942
------------------
The regression equation I get is y = 1.323077x+1.584615
--------
Using stand. error of the estimate =sqrt[ summation[(y-yhat)^2/(n-2)]] I 
get an answer of 0.769615.
-----------------------------
My TI does not calculate the confidence interval.  Hopefully the software
you have does that for you.
