QUESTION 2 Use minitab Suppose a sample of 20 students were given a diagnostic test before studying a particular module and then again after completing the module. We want to find out if, in general, our teaching leads to improvements in students' knowledge/skills (i.e. test scores). We can use the results from our sample of students to draw conclusions about the impact of this module in general. 92.MPJ 1) check assumption (fort show your correct 3) find the t-value...

A study was conducted to determine success rates of students
enrolled in the Statistics courses offered at South Plains College
for the fall semester of 2015. A random sample of 14 students was
taken, and we recorded each
student’s age, final average, gender, # hours worked per week,
race, and the attendance record (# of classes not attended this
semester). Use the results from the following table to answer all
parts of #2
f. For the age variable, construct 3...
