If the p-value = 0.4567, then which of the following is true.
A. We fail to reject Ho at a significance level = .05
B. We fail to reject Ho at a significance level = .10
C. We fail to reject Ho at a significance level = .01
D. All of these answers are correct
When choosing between a biased but very efficient estimator and an unbiased but very inefficient estimator, we should choose the one with the minimum Mean Square Error.

Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the alternative that it is not at a level of significance of 5% and a sample size of n=151. We calculate a test statistic = -1.655. The p-value of this hypothesis test is approximately . (Write your answer out to two decimal places. In other words, write 5% as 0.05.)

The p-value for a hypothesis test is shown Use the P-value to decide whether to re ed HO when the level of significance is a)a:0。1 b 0 05 and c r:0 10. P 0.0612 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Fal to reject Ho because the P-value, o 0612, is less than α-Ο 01. O B. Reject Ho because the P.value, 0.0612, is less than a-0.01 О с. Fail...
Question 1 (1.5 points) Decide in each case wether to reject Ho or fail to reject Ho. P-value = .05 Level of significance = 0.01 P-value = 0.02 Level of significance = 0.01 P-value = 0.04 Level of significance = 0.1 P-value = 0.002 Level of significance = 0.05 Fail to reject the null hypothesis Reject the null hypothesis P-value = P-value = .05 Level of significance = 0.01 P-value = 0.02 Level of significance = 0.01 Fail to reject...
Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the alternative that it is not at a level of significance of 5% and a sample size of n=151. We calculate a test statistic = -1.976. The p-value of this hypothesis test is approximately ? . (Write your answer out to two decimal places. In other words, write 5% as 0.05.)
The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject H when the level of significance is (a) a= 0.01, (b) a 0.05, and (c) a0.10. P 0.0749 (a) Do you reject or fail to reject Ho at the 0.01 level of significance? O A. Reject H because the P-value, 0.0749, is greater than a=0.01 O B. Fail to reject Ho because the P-value, 0.0749, is less than a = 0.01 O C. Reject...
Question 5 2 pts Which of the following statements is true? (a) we reject a null hypothesis if the p-value of the test is smaller than the level of the significance a.

(c) we reject a null hypothesis if the p-value of the test is larger than the level of the significance a. . (a) . (b) . (c)
A test of hypothesis is conducted and the p-value is .11. This means we ______ A. Reject the null hypothesis at the .01 level B. Reject the null hypothesis at the .05 level but not the .01 level C. Reject the null hypothesis at the .10 level but not at the .05 level D. Fail to reject the null hypothesis at the .10 level
Consider the following point estimators, W, X, Y, and Z of μ: W = (x1 + x2)/2; X = (2x1 + x2)/3; Y = (x1 + 3x2)/4; and Z = (2x1 + 3x2)/5. Assuming that x1 and x2 have both been drawn independently from a population with mean μ and variance σ2 then which of the following is true...Which of the following point estimators is the most efficient? A. Z B. W C. X D. Y An estimator is unbiased...
Which of the following statements is true? I. If the p-value is 0.01, we reject H0 for any alpha level less than 0.01. II. If we use an alpha level of 0.05, then a p-value of 0.005 is not statistically significant. III. If we use an alpha level of 0.05, then we fail to reject the null hypothesis if the p-value is 0.1.
