Start by question 10

Regression
 Relation  last column
 Predict
 Y=aX+b
 ^Y= .571X+3.093
 With X = 4  Y = 5.377

Correlation
 How further from the 0, how stronger the correlation is.

T-test
 Difference in mean
 Is there a difference?
 Is it significant?  not correct (P > .05)  same row
 Is it significant?  correct (P < .05)  row downside, naar beneden
 There is a significant difference in spending between IHM and no IHM students
(t=2.248; df=298; P=.025),

Chi-squire
 45.4% of the fantasy likes are male.
 There is a significant relation between gender and kind of movie (X2=18.058; DF = 3;
P = .000).

Null hypothesis
_
X  gemiddelde
 H0 : Xif = Xcanteen
 Null hypothesis  gelijk aan elkaar
 Alternative hypothesis  niet gelijk aan elkaar
 H1 : Xif ≠ Xcanteen
 H0 : there is no relation
 H1 : there is a significant relation
