Focusing on Axioms Resolution: UWEC Undergraduates
The refine determined Standpoint.txt in the standpoint axiomsbase exception of the WeissStats residence contains counsel on the undergraduate students at the University of Wisconsin – Eau Claire (UWEC). Those students compose the population of camanifestation in the Standpointing on Axioms Resolution exceptions that show at the purpose of each chapter of the quantity.
Thirteen capriciouss are considered. Table 1.9 lists the capriciouss and the names manifestationd control those capriciouss in the axioms refines. We fawn the axiomsbase of counsel control those capriciouss the standpoint axiomsbase.
Also granted in the Standpoint Axiomsbase exception is a refine fawned StandpointSample.txt that contains axioms on the similar 13 capriciouss control a ultimate purposeless exemplification of 200 of the undergraduate students at UWEC. Those 200 students compose a exemplification that can be manifestationd control making statistical interferences in the standpointing on axioms resolution exceptions. We fawn this exemplification axioms the Standpoint exemplification.
Large axioms sets are almost frequently stird by computer, and that is how you should manifestation twain the Standpoint axiomsbase and the standpoint exemplification. We own gifted the Standpoint axiomsbase and Standpoint Exemplification in diverse refine controlmats in the Standpoint Axiomsbase exception of the WeissStats residence.
If you manifestation a statistical software package control which we own not attributable attributable attributable gifted a Standpoint axiomsbase refine, you should (1) input the refine Standpoint.txt into that software, (2) determine that the capriciouss are determined as implied in Table 1.9, and (3) secure the worksheet to a refine determined Standpoint in the controlmat alienate to your software, that is, with the alienate refine production. Then, any era that you shortness to stir the Standpoint axiomsbase, you can barely regain your Standpoint worksheet. These similar remarks apportion to the Standpoint exemplification, as well-behaved-behaved as to the Standpoint Axiomsbase.

a.) Find the direct mutuality coefficient between cumulative GPA and noble ground percentile control the 200 UWEC undergraduate students in the Standpoint Exemplification.
b.) Repeat bisect (a) control cumulative GPA and each of ACT English beak, ACT math beak, and ACT comporesidence beak.
c.) Among the capriciouss noble ground percentile, ACT English beaks, ACT math beak, and ACT comporesidence beak, test the individual that shows to be the best predictor of cumulative GPA. Explain your forced.
Now discharge a return resolution on cumulative GPA, using the predictor capricious identified in bisect (c), as follows.
d.) Obtain and expone a scatterplot
e.) Find and expone the return equation
f.) Find and expone the coefficient of determination
g.) Determine and expone the 3 sums of squares SSR, SSE, and SST.
