Using the dataset $$Mini$-$project $2$ Dataset.xls$,$ answer the following research questions. Develop associated hypotheses to help answer the research questions. Be sure to address important regression assumptions as well.

$1.$ Is HSGPA a significant predictor of ST$\_$GPA$1$ controlling for HSUNITS, BESTTEST, and GENDER?

$2.$ Is HSUNITS a significant predictor of ST$\_$GPA$1$ controlling for HSGPA, BESTTEST, and GENDER?

$3.$ Is BESTTEST a significant predictor of ST$\_$GPA$1$ controlling for HSUNITS, HSGPA, and GENDER?

$4.$ Is GENDER a significant predictor of ST$\_$GPA$1$ controlling for HSUNITS, BESTTEST, and HSGPA?

$5.$ Is there an interaction effect between GENDER and BESTTEST using ST$\_$GPA$1$ as the dependent variable controlling for HSUNITS and HSGPA?

$6.$ Is there a non$-$linear squared effect for BESTTEST using ST$\_$GPA$1$ as the dependent variable controlling for HSUNITS, HSGPA, and GENDER?

Reports will include the following three sections:

$1.$ Introduction

$2.$ Results

$3.$ Conclusions

Grades will be determined using the following equally$-$weighted criteria:

$$ Accuracy: Data are analyzed using the correct tests and the procedure yields the correct results.
