Question

Determine the critical values for the following tests of the population mean with an unknown population standard deviation. The analysis is based on 7 observations drawn from a normally distributed population at a 5% level of significance. Use Table 2. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.)

a.

H0: 51 versus HA: > 51

Determine the critical values for the following tests of the population mean with an unknown population standard deviation.

Explanation / Answer

a.
H0: 51 versus HA: > 51

ANS.
The Value of |t | with n-1 = 6 d.f, right tailed is 1.943

b.
H0: = 9.4 versus HA: 9.4

ANS.
The Value of |t | with n-1 = 6 d.f is +2.447, -2.447

c.
H0: 4.6 versus HA: < 4.6

ANS.
The Value of |t | with n-1 = 6 d.f, right tailed is -1.943

d.H0: = 14 versus HA: 14

ANS.
The Value of |t | with n-1 = 6 d.f is +2.447, -2.447
