Question
MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis.
Professor Diff E. Cult wonders if male and female students earn significantly different grades when taking the same course with the same instructor. He randomly samples 160 males and 100 females from selected classes. The males receive 20 As, 32 Bs, 70 Cs, 30 Ds, and 8 Fs. The
females receive 20 As, 28 Bs, 30 Cs, 10 Ds, and 12 Fs. His hypothesis is that gender and grades are related.
Choose the type of test you should use to test this hypothesis?
Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).
O z-test
single sample t-test
dependent t-test
O independent t-test
Pearson correlation t-test
ANOVA
O Chi-Square Goodness of Fit Test
Chi-Square Test of Independence
O Ho: H1 - P2 = 0
H1: P1 - P2 # 0
O Ho: µ1 - P2 < 0
