Question

Hypothesis: Students spend an average of 35 hours per week studying

H0 : μ = 35

H1 : μ ≠ 35

Sample data:

X̄= 27.71 hours

n=34

p= 0.815

Test values:

z= -4.751

p= 0.0001

np > 10 n(1-p) > 10

34*0.815 = 27.71

34*(1-0.815) = 6.29

Do I fail to reject the hypothesis or do I reject a hypothesis?

Can you please explain, thank you
