Question 395263: Looking for help with the following:
Using the p-value from Question #1, would you accept or reject the null hypothesis at the 95% confidence level? Why or why not?
Note: Question #1 is:
Provide the p-value for a left-tailed one sample hypothesis test (z test) where the test statistic is -2.6. You must show your work or provide the Excel formula that you used.

Thanks!

You can put this solution on YOUR website!
the pvalue for z test statistic of -2.6 is 0.00047

Since the pvalue is less than the significance level 0.05, then reject Ho.

The pvalue represent the probability that the test statistic, assuming Ho is true deviated from Ho by pure chance. Since this probablity is small, you conclude that it is evidence that it does not come from Ho.
