Question
For each setting indicate the appropriate statistical decision:
Note: one submission per part
A) Ho: 160 vs Ha: > 160
n = 16; alpha = 0.05 and ttest = 0.91
---Select--- Reject Ho, Fail to reject Ho
B) Ho: 190 vs Ha: < 190
n = 12; alpha = 0.01 and ttest = -3.81
---Select--- Reject Ho, Fail to reject Ho
C) Ho: = 140 vs Ha: 140
n = 7; alpha = 0.1 and ttest = 2.43
---Select--- Reject Ho, Fail to reject Ho
D) Ho: 160 vs Ha: > 160
n = 10; alpha = 0.025 and ttest = 1.36
---Select--- Reject Ho, Fail to reject Ho
E) Ho: 175 vs Ha: < 175
n = 15; alpha = 0.05 and ttest = -1.95
---Select--- Reject Ho, Fail to reject Ho
F) Ho: = 180 vs Ha: 180
n = 20; alpha = 0.02 and ttest = 4.19
---Select--- Reject Ho, Fail to reject Ho
Explanation / Answer
A) Ho: 160 vs Ha: > 160
n = 16; alpha = 0.05 and ttest = 0.91
df = n-1 =15
Answer : The P-Value is .188607
Since p value is greater than level of significance we fail to reject H0
b) Ho: 190 vs Ha: < 190
n = 12; alpha = 0.01 and ttest = -3.81
df = n-1 =11
Answer : The P-Value is 0.001446
Since p value is less than level of significance we reject H0
C) Ho: = 140 vs Ha: 140
n = 7; alpha = 0.1 and ttest = 2.43
df = n-1 =6
Answer : The P-Value is 0.051162
Since p value is less than level of significance we reject H0
D) Ho: 160 vs Ha: > 160
n = 10; alpha = 0.025 and ttest = 1.36
df = n-1 =9
Answer : The P-Value is 0.103459.
Since p value is greater than level of significance we Fail to reject H0
E) Ho: 175 vs Ha: < 175
n = 15; alpha = 0.05 and ttest = -1.95
df = n-1 =14
Answer : The P-Value is 0.035746.
Since p value is less than level of significance we reject H0
F) Ho: = 180 vs Ha: 180
n = 20; alpha = 0.02 and ttest = 4.19
df = n-1 =19
Answer : The P-Value is 0.000497
Since p value is less than level of significance we reject H0
