True or false. Can a test one sample hypotheses test about the mean with a confidence interval about the mean?

your question is not very clear.





it is possible to draw the sample conclusions from a confidence interval and hypothesis test.





if you find a 100(1 - 伪)% confidence interval then for any value of 渭, the population mean, within the CI, you will fail to reject the null hypothesis that 渭鈧€ = 渭 at the .伪% significance level





for any value of 渭 outside of the confidence interval you would reject the null hypothesis at the corresponding significance level.
