A: Knowledge of whether the test is one-tailed or two-tailed
B: The value of the test statistic
C: The level of significance
D: Sample size
举一反三
- If the p-value of a test statistic is .20 and the level of significance is .05, the null hypothesis should be rejected.
- An unbiased estimator is a sample statistic, which has an expected value equal to the value of the population parameter.
- The correct value of the test statistic is A: 2.02 B: - 2.91 C: 0.458 D: 4.02
- The correct value of the test statistic is A: 47.4 B: -6.70 C: 3.19 D: -0.36

In a test of H0 : μ = 200 against HA : μ ≠200, a sample of size 10 produces a sample mean of 206 and a p-value of 0.09. Thus, at the 0.05 level of significance: (H0 is the null hypothesis, HA is the alternative hypothesis) ( ) A: there is sufficient evidence to conclude that μ≠200 B: there is sufficient evidence to conclude that μ = 206 C: there is insufficient evidence to conclude that μ = 200 D: there is insufficient evidence to conclude that μ≠200.

The test statistic measures how close the computed sample statistic has come to the hypothesized population parameter.
