Determine the critical values for the following tests of the
Determine the critical values for the following tests of the population mean with an unknown population standard deviation. The analysis is based on 27 observations drawn from a normally distributed population at a 10% level of significance. Use Table 2. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.)
a.
H0: 37 versus HA: > 37
| Critical Value | ||
| a. | H0: 37 versus HA: > 37 | |
| b. | H0: = 12.3 versus HA: 12.3 | ± |
| c. | H0: 6.7 versus HA: < 6.7 | |
| d. | H0: = 13 versus HA: 13 | ± |
Solution
a)
The Value of |t | with n-1 = 26 d.f is 1.315
b)
The Value of |t | with n-1 = 26 d.f is +1.706,-1.706
c)
The Value of |t | with n-1 = 26 d.f is -1.315
d)
The Value of |t | with n-1 = 26 d.f is +1.706,-1.706
