Review(32a);
CHOOSE two options.
Professor Ratzo wonders if rats will run a maze faster for some kinds of foods rather tha others.
He randomly assigns 30 rats to one of three conditions. Group1 gets bread at the end of the maze.
Group2 gets cheddar cheee and Group3 gets honey glazed ham. The number of seconds was
recorded. The hypotheseis is that type of food makes a difference in rat running time.
Choose the correct hypotheses in symbol notation(or word if symbol is not available)
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
