Question
Which test is used for testing the significance of mean differences?
Solution
The t-test is used for testing the significance of mean differences. Here are the steps to perform a t-test:
-
Formulate the Null Hypothesis (H0): The null hypothesis for a t-test typically states that there is no significant difference between the means of two groups.
-
Formulate the Alternative Hypothesis (H1): The alternative hypothesis states that there is a significant difference between the means of the two groups.
-
Choose the Significance Level: The significance level, often denoted by alpha (α), is the probability of rejecting the
