Since you performed a two-sided hypothesis test for using
?=0.05, and you created a 95% confidence interval
for ,
(a) What value of ? would you be testing at if you had constructed a 98% confidence interval?
?=0.02
(b) Also, what type of test would you be performing?
what is the answer to part B?

The p-value for a two-sided hypothesis test is 0.05 for the null hypothesis Ho: μ = 15. Does the 99% confidence interval associated with the test include the value 15? (Click to select)YesNoUnable to determine
A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis
49. The p-value for a two-sided hypothesis test of the null hypothesis Ho: μ = 12 is 0.07. Which of the following confidence intervals would include the value 12? 1. 90% Confidence Interval 2. 95% Confidence Interval 3. 99% Confidence Interval a. 1 and 2 b. 2 and 3 c. 1 only d. 1, 2, and 3 e. Impossible to Determine
The p-value for a two-sided hypothesis test is 0.04 for the null hypothesis Ho: μ = 15. Does the 95% confidence interval associated with the test include the value 15? YES, NO, OR UNABLE TO DETERMINE?
Can someone explain why the answer is B
please?
Exercise The p-value for a two-sided test of the null hypothesis, Ho: u = 10 was found to be 0.06. Therefore, using the same data, A) a 90% confidence interval would contain the value of 10. B) a 95% confidence interval would contain the value of 10. C) Both 90% and 95% confidence interval would contain the value of 10. D) Neither 90% nor 95% confidence interval would contain the value...
30 is 0.037. Does the 95% 3. (1 pt) The p-value for a two-sided test of the null hypothesis Ho: confidence interval include the value 30? Explain.
You conduct a two-sided hypothesis test (a=0.05), and obtain a Z-score equal to -2.3 (N is large) Which of the following statements are ALWAYS true? 1. You reject the null hypothesis Ho II. The resulting p-value is 0.0215 III. You have made a Type I Error. All of the Above I only I and Ill only I and II only Ill only

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.
Suppose a test of H0: μ = 0 vs. Ha: μ ≠ 0 is run with α = 0.05 and the P-value of the test is 0.052. Using the same data, a confidence interval for μ is also constructed. (a) Of the following, which is the largest confidence level for which the confidence interval will not contain 0? 90% 94% 95% 96% 99% (b) Of the following, which is the smallest confidence level for which the confidence interval will contain...
