In a test of H0: µ=150 against HA: µ<150, a sample of size 250 produces Z = -0.65 for the value of the test statistic. Thus the p-value is approximately equal to:
Find the p-value for the t-test of Ho: µ = 4 vs. Ha: µ > 4 where n = 11 and t = 2.646. Report 4 decimal places.
Find the value of the test statistic, z⋆, for the following hypothesis test and p-value. H0: ? = 28, Ha: ? ≠ 28, p-value = 0.0208
The five parts are: i. Null Hypothesis: H0 : µ =5.2 ii. Alternative Hypothesis: HA : µ < 5.2 iii. Rejection Region: Reject H0 if t statistic <−t49,.05 =−1.677 iv. Test Statistics: t = Y−µ0 S/pn = 5−5.2 0.7/p50 =−2.0203 <−t49,.05 =−1.677 v. Conclusion. Reject H0 at α = 5%. The data support that the mean dissolved oxygen count of the water is less than the reading at this location over the past year. What is the p-value?
Suppose the null hypothesis is Ho : µ = 500 against Ha : > µ = 500 , and the significance level for this testing is 0.05. The population in question is normally distributed with standard deviation 100. A random sample of size n=25 will be used. If the true alternative mean is 550, then the probability of committing the type II error is ____.
Given Ha ≠ p0. What is the P-value if the test statistics is calculated to be z = -0.12? A) 0.90 B) 0.95 C) 0.12 D) 0.10 E) 0.05
Consider the following hypothesis test: Ho: µS 12 Ha: µ > 12 A sample of 25 provided a sample mean 14 and a sample standard deviation s= = 4.32. a. Compute the value of the test statistic (to 2 decimals). 2.31 b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. The p-value is less than .005 Answer the next three questions using the critical value approach. C. Using a = 0.05,...
