MAKE SURE YOU SELECT TWO ANSWERS FOR THIS QUESTION.. Type of test and hypotheses.
Professor dill wonders if male and female earn significantlly differnent grades, when taking the same
course with the same instructor. He randomly samples 160 males. and 100 females. The males
receive 20 A's, 32 B's 70 C's 30 D's, anf 8 F's.The female receive 20'A's, 28 B's, 30 C's, and 10 D's.
and 12 F's; His hypotheses is that gender and grades are related.
Choose the type of test you should choose to test the hypotheses in symbol notation( or in words
if symbol is not appropriate)
(a) Z test
(b)single sample t test
(c)dependent t test
(d) independent t test
(e) Pearson
(f) ANOVA
(g) chi Square goodness of fit test
(h)Chi Square test of independence
(i) Ho: u1-u2=0
H1: u1-u2!=0
(j) Ho: u1-u2 =0
H1:u1-u2<0
(k) Ho: u1-u2 >= 0
H1: u1=u2<0
(l) Ho : Rho=0
H1: Rho!=0
(m) Ho: Rho >= 0
H1: Rho <0
(n) Ho:Rho <= 0
H1: Rho > 0
(o) Ho: u=0
H1: u<=0
(p) Ho: u<=0
H1: u>0
(q) Ho:u>=0
H1: u<0
(r) Ho:The two variables are independent
H1: THe two variables are dependent/related
