A researcher is using a two-tailed hypothesis test with α = 0.01 to evaluate the effect of a treatment. If theboundaries for the critical region are t = ± 2.845, then how many individuals are in the sample?A. n = 23B. n = 22C. n = 21D. n = 20E. cannot be determined from the information given
Suppose that a t-test is being conducted at the 0.05 level of significance to test H0: mu=50 versus Ha:mu<50. A sample of size 20 is randomly selected. The rejection region is:
A.
t < 2.086
B.
t < -1.729
C.
t > -2.093
D.
t > 1.725
For a hypothesis test of H0:μ=μ0H0:μ=μ0 against the alternative Ha:μ<μ0Ha:μ<μ0, the z-test statistics is found to be 2.00. This finding is
a.significant at neither the 0.01 nor the 0.05 levels.
b.significant at the 0.01 level but not at the 0.05 level.
c.significant at both the 0.01 and the 0.05 levels.
d.not large enough to be considered significant.
e.significant at the 0.05 level but not at the 0.01 level.
