H1:p<0.575H1:p<0.575
H1:p<0.575H1:p<0.575
b.)
H0:p=0.575H0:p=0.575
H1:p≠0.575H1:p≠0.575
H1:p≠0.575H1:p≠0.575
c.)
H0:p=0.575H0:p=0.575
H1:p>0.575H1:p>0.575
H1:p>0.575H1:p>0.575
d.)
H0:μ=2.3H0:μ=2.3
H1:μ≠2.3H1:μ≠2.3
H0:μ=2.3H0:μ=2.3
H1:μ≠2.3H1:μ≠2.3
e.)
H0:μ=2.3H0:μ=2.3
H1:μ>2.3H1:μ>2.3
H0:μ=2.3H0:μ=2.3
H1:μ>2.3H1:μ>2.3
f.)
H0:μ=2.3H0:μ=2.3
H1:μ<2.3H1:μ<2.3
H1:μ<2.3H1:μ<2.3
The test is:
a.)left-tailed
b.)right-tailed
C.)two-tailed
Based on a sample of 75 people, the sample mean GPA was 2.35 with a standard deviation of 0.05
The test statistic is: (to 2 decimals)=
The critical value is: (to 2 decimals)=
Based on this we:
A.)Reject the null hypothesis
B.)Fail to reject the null hypothesis
