a particular pre-selected value of the population mean, µ0, and a pre-selected significance level (such as 0.05). The test's result would be based on the value of the observed sample
The formula returns the value 0.03098. This is the p-value. You reject the null hypothesis if this value is less than your level of significance alpha. So if your level of significance is .05, you would reject it, but not if your level of significance is .025 or .01. The test for ...
