For ALL problems, state hypotheses, in words andsymbols and give me everything listed below. Use SPSS whenappropriate but DO NOT print out and turn in SPSSoutput.  Instead, just read the criticalinformation out of SPSS and report: obtained t-statistic,probability of obtaining that statistic under the null(p-value), decision to reject null or not, interpretationof results in words, and report measure of effect size ifappropriate.
- I want to know if rats with an exercise wheel in their cagesend up healthier (less chubby) than rats without.  I knowthe average weight of rats without exercise wheels is 402grams.  I take 10 rats and put an exercise wheel in theircages.  Then after a month, I weigh them and get theseweights in grams:
Wheel group: 320, 240, 400, 390, 270, 300, 320, 409, 380,460
- I want to know if wall color affects test scores.  Irandomly assign 5 students to either the blue wall group or the redwall group.  The blue group gets test scores of 87, 99,76, 87, 80 while the red wall group gets 88, 85, 90, 76, 87.
