Now we can run the one-sample t-test, knowing the data are normally distributed. If the data are not normally distributed, you need to use hypothesis tests other than the one sample t-test. Since the p-value of the normality is 0.275, which is greater than alpha level (0.05), we fail to reject the null and claim that the data are normally distributed.
