Question 457487
I'm assuming that Z* is the test statistic (it could easily be the critical value). Without more information, I cannot verify if that is the correct value for the test statistic (since I would need to know x1, x2, n1, and n2)



Ignoring these little details, if Z* = 1.73 is the test statistic, then you are correct in saying that the p-value is 0.0836



Now if your significance level alpha is 0.01 or 0.05, then you would fail to reject the null hypothesis (since the p value is larger than alpha).



On the other hand, if the significance level alpha is something like 0.1, then you would reject the null hypothesis (since the p-value is smaller than alpha).



If the significance level is not stated or given, then assume it to be 0.05 (usually the default significance level in many cases)



Overall, it seems like a lot of info is missing. Please post more info if you can.
