The null and alternative hypothesis would be:
H0:μ=2H0:μ=2
HA:μ≠2HA:μ≠2
HA:μ≠2HA:μ≠2
H0:p≤0.5H0:p≤0.5
HA:p>0.5HA:p>0.5
HA:p>0.5HA:p>0.5
H0:p≥0.5H0:p≥0.5
HA:p<0.5HA:p<0.5
HA:p<0.5HA:p<0.5
H0:μ≥2H0:μ≥2
HA:μ<2HA:μ<2
HA:μ<2HA:μ<2
H0:μ≤2H0:μ≤2
HA:μ>2HA:μ>2
HA:μ>2HA:μ>2
H0:p=0.5H0:p=0.5
HA:p≠0.5HA:p≠0.5
HA:p≠0.5HA:p≠0.5
The test is:
right-tailed
two-tailed
left-tailed
Based on a sample of 50 people, the sample mean GPA was 1.95 with a standard deviation of 0.05
The p-value is: (to 2 decimals)
Based on this we:
- Reject the null hypothesis
- Fail to reject the null hypothesis
