How does the 95% confidence interval correspond to the reported conclusion at a 0.05 significance level?

  

The confidence interval contains the value of ‘0’, and the results of the test were statistically significant.

   

The confidence interval contains the value of ‘0’, and the results of the test were not statistically significant.

   

The confidence interval does not contain the value of ‘0’, and the results of the test were statistically significant.

   

The confidence interval does not contain the value of ‘0’, and the results of the test were not statistically significant.

Answer #1

The hypothesis test is statistically significant. If the confidence interval does not contain the null hypothesis value, the results are statistically significant.

if Confidence level does not contains null hypothesis value,we reject null hypothesis hence results are statistically significant

if we failed to reject H0, results are not significant

The confidence interval contains the value of ‘0’, and the results of the test were not statistically significant.  

The confidence interval does not contain the value of ‘0’, and the results of the test were statistically significant.

Significane Level of a=0.05 is used for each hypothesis test and a confidence level of 95% is used for each confidence interval estimate. A random sample of people who work regular 9-5 hours and a random sample of people who work shifts were asked how many hours of sleep they get per day on average. An appropriate F-Test was performed and it was found that the null hypothesis of the F-Test should be rejected. Can we infer that there is...

In the following exercise, use a significance level of α = 0.05 to State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0 ) Without using technical terms or symbols, state a conclusion that addresses the original claim. Original Claim: More than 58% of adults would erase all their personal information online if they could. The hypothesis test results in a P-value of 0.3257.

Suppose you calculate a 95% confidence interval for the difference in population means. The confidence interval contains both negative and positive values. Will a 99% confidence interval based on the same data contain both negative and positive numbers as well? Choose the correct response from the options provided below. Yes. Keeping all other values the same, increasing the confidence level leads to a wider interval which would still include negative and positive numbers. No. Increasing the confidence level leads to...

A study was reported as failing to achieve statistical significance at the 5% level: its p-value was 5.2%. A second study of the same subject by a different researcher was determined to be statistically significant, with p-value 4.99%. The two studies found the same estimate for the mean difference and were of equal quality. Q. Discuss how you would view the results. (using statistic knowledge and terminology)

Please criticize the following statement regarding the interpretation of a confidence interval: Results for a 95% Confidence Interval for estimating the population mean: 74.1< Mean< 83.1 " After looking at the above results we can conclude that there is a 95% chance that the confidence interval contains the true mean of the population" Is the above statement correct? Why? If it is not correct how can we re-state the conclusion in order to interpret correctly the above confidence interval?
