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
