4. At the 0.05 level, can we conclude there is a difference between the students’ fall
weight and spring weight?
Draw a random sample from the 67 college students, carefully explaining
your procedure.
YOU MUST USE a different “random” method this time
your sample must consist of 10 students, not 20-29
Determine whether your sample provides statistical evidence that
there is a difference between the students’ fall weight (before) and
spring weight (after). Set alpha at 0.05.
Adding on to the written report above, address question 4!
o Note: It may be wise to use a hypothesis testing sheet (nice
handwriting, etc…) to help with your report.
