A hypothesis test is performed of the null hypothesis H0 :μ = 0. The P-value turns out to be 0.03.
Is the result statistically significant at the 10% level?
[a]
Is the result statistically significant at the 5% level?
[b]
Is the result statistically significant at the 1% level?
[c]
If P value
................then we reject H0
We have given,
P value =0.03
a) Yes
b) Yes
c) No , since P value >0.01

(a) Suppose the null and alternative hypothesis of a test are: H0: μ= 9.7 H1: μ >9.7 Then the test is: left-tailed two-tailed right-tailed (b) If you conduct a hypothesis test at the 0.02 significance level and calculate a P-value of 0.07, then what should your decision be? Fail to reject H0 Reject H0 Not enough information is given to make a decision
Based on the sample data, the P-value for a two-sided test of the null hypothesis H0:μ=10H0:μ=10 vs. H1:μ≠10H1:μ≠10 is 0.06. Which of the following statements is correct? A. the 95% confidence interval includes the value 10 B. the 68% confidence interval includes the value 10 C. the 90% confidence interval includes the value 10 D. None of the above

A test of the null hypothesis H0: μ = μ0 gives test statistic z = 0.45. (Round your answers to four decimal places.) (a) What is the P-value if the alternative is Ha: μ > μ0? (b) What is the P-value if the alternative is Ha: μ < μ0? (c) What is the P-value if the alternative is Ha: μ ≠ μ0?
A test of the null hypothesis H0: μ = μ0 gives test statistic z = 0.66. (Round your answers to four decimal places.) (a) What is the P-value if the alternative is Ha: μ > μ0? (b) What is the P-value if the alternative is Ha: μ < μ0? (c) What is the P-value if the alternative is Ha: μ ≠ μ0?
We test the null hypothesis H0: μ = 10 and the alternative Ha: μ ≠ 10 for a Normal population with σ = 4. A random sample of 16 observations is drawn from the population and we find the sample mean of these observations is = 12. The P-value is CLOSEST to: A. 0.9772. B. 0.0456. C. 0.0228. D. 0.6170.
9. A hypothesis test is performed with a significant level of á05 a) If the P-value is.08, is Ho rejected?7 b) If the P-value is .08, are the results statistically significant at 05 level? c) If the P-value is.03, is Ho rejected? d) If the P-value is .03, are the results statistically significant at 05 level?
A test of H0: μ = 50 versus H1: μ ≠ 50 is performed using a significance level of α = 0.01. The value of the test statistic is z = 1.23. a. Is H0 rejected? b. If the true value of μ is 50, is the result a Type I error, a Type II error, or a correct decision? A test of H0: μ = 50 versus H1: μ ≠ 50 is performed using a significance level of α...
