**1. The Instructor of the Stat_Grades.sav class
decided to provide additional opportunities for the students in the class to
learn the class materials. To accomplish this, the Instructor offered all
students the option to attend a set of review sessions. The Instructor believes
that offering these review sessions will help student performance. Using the
appropriate tests, methods, and evaluations, determine if attending the Review
sessions made a significant difference in students Total Course Points. Be sure
to include each step of the process, any SPSS results used, an interpretation
of the results, and final conclusions. **

experience, the Instructor for the Stat_Grades.sav class has determined that a
Percent for the Course of 85% describes a successful class. Does the
Instructor’s current Stat_Grades.sav Percent for the Course differ
significantly from what is considered to be normally successful? Use and
include the appropriate tests, methods, and evaluations. Be sure to include
each step of the process, any SPSS results used, an interpretation of the
results, and final conclusions.**

**3. Using the Stat_Grades.sav dataset for
students, compare Quiz 1 and Quiz 3 and determine if there is a statistically
significant difference in the average student performance between these two
quizzes. Use and include the appropriate tests, methods, and evaluations. Be
sure to include each step of the process, any SPSS results used, an interpretation
of the results, and final conclusions.**
