Step 1
The null hypothesis in this case would be that the true population mean is equal to a specified value, μ0. In a one-sample z-test, this value is often taken to be the hypothesized value of the population mean. The null hypothesis in this case would be μ = 10. The sample mean of 10 and the population standard deviation of 2 are used to calculate a z-statistic and a p-value, which are then used to determine whether to reject or fail to reject the null hypothesis.
