Answer:
A. This is a two tailed test.
B. H0: μ= 73.5
C. P-value= 0.196
D. The P-Value is 0.460172 for one tailed test .
Step-by-step explanation:
The given data is
Variable N Mean StDev SE Mean 95% 01 Z P
X 145 73.2461 2.3634 0.1963 (72.8614, 73.6308) -1.29 0.196
A. Is this a one-tailed or two tailed test?
This is a two tailed test because H0: μ= 73.5 against Ha: μ ≠ 73.5
B. What is the null hypothesis?
H0: μ= 73.5
C. What is the P-value?
P-value= 0.196
D. Use the output to compute the P-value for the test of H0 : μ ≥ 73.6 versus H1 : μ < 73.6.
For z= -1.29 the P-Value is 0.460172 for one tailed test .
The result is not significant at p < 0.05.
