Question

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 ±
