You are determining if two sets of data are significantly different from one another by using Azure Machine Learning Studio. Estimated values in one set of data may be more than or less than reference
The correct answer is D. Unpaired t-test with a one-tail option. Choose a one-tail or two-tail test. The default is a two-tailed test. This is the most common type of test, in which the expected distribution is symmetric around zero. Example: Type I error of unpaired and paired two-sample t-tests as a function of the correlation. The simulated

Explanation
Choose a one-tail or two-tail test. The default is a two-tailed test. This is the most common type of test, in which the expected distribution is symmetric around zero. Example: Type I error of unpaired and paired two-sample t-tests as a function of the correlation. The simulated random numbers originate from a bivariate normal distribution with a variance of 1. https://docs.microsoft.com/en-us/azure/machine-learning/studio-module-reference/test- hypothesis-using-t-test https://en.wikipedia.org/wiki/Student%27s_t-test
