Question

Let p1 be the proportion of residents in Country A coping with depression, and let p2 be the proportion of residents in Country B coping with depression. What is the null hypothesis for a test to determine whether Country A has a greater proportion of residents coping with depression than Country B?

a. H0: p1âp2>0
b. H0: p1âp2<0
c. H0: p1âp2=0
d. H0: p1âp2â 0

Answer 1

H0 : p1 = p2

Explanation:

Null Hypothesis is the general default statement, stating no difference between phenomena.

To test whether country A has higher proportion of residents coping with depression -

Null [ H0 ] : Proportionate depressed people are equal. p1 = p2

Alternate [ H1 ] : Proportionate depressed people in country A > in country B

p1 > p2
