The information from #2 is: Z a/2=1.960 CI=(0.7446,0.8554) I attached question #2 for reference but need #5 answered.
Let π denote some population proportion of interest and suppose a 99% confidence interval for π is calculated to be (0.60, 0.70). Also, suppose we want to test the hypotheses H0:π=0.74 and HA:π≠0.74 . What can you say about the corresponding p-value? The corresponding p-value will be smaller than 0.01. The corresponding p-value will be smaller than 0.05 but larger than 0.01. The corresponding p-value will be larger than 0.05. I can't say anything about the corresponding p-value until I run the test.
Suppose you are testing the hypotheses H0:μ=10 and Ha:μ≠10, and the p−value is 0.06. Would a 90% confidence interval for μ include the value 10? Answer choices: No. A p−valuep−value of 0.06 indicates that the results observed are statistically significant at the 10% level, so the 90% confidence interval will not include 10. No. A p−valuep−value of 0.06 indicates that the results observed are not statistically significant at the 10% level, so the 90% confidence interval will not include 10. Yes. A p−valuep−value of 0.06 indicates that the results observed are statistically significant at the 10% level, so the 90% confidence interval will include 10. Yes. A p−valuep−value of 0.06 indicates that the results observed are not statistically significant at the 10% level, so the 90% confidence interval will include 10.
