Question
The paired t-test is essentially ...Question 2Answera.A two-sample t-test with the null hypothesis that the two means are differentb.A two-sample t-test with the null hypothesis that the two means are equalc.A one-sample t-test with the null hypothesis that the difference scores have a mean equal to the higher scored.A one-sample t-test with the null hypothesis that the difference scores have a mean of 0
Solution
The correct answer is d. A one-sample t-test with the null hypothesis that the difference scores have a mean of 0.
Here's why:
The paired t-test is a type of t-test that is used when the same subjects are used for each treatment. That is, it is a test that compares two related or matched groups.
The null hypothesis for a paired t-test is that the mean difference between the paired observations is zero. In other words, it assumes that the average of the difference between all pairs of observation is zero.
So, the paired t-test is essentially a one-sample t-test with the null hypothesis that the difference scores have a mean of 0.

There is a hypothesis that Virat Kohli performs better or as good in the second innings of a test match as the first innings. This would be a two-sample mean test. This means that sample 1 and 2 would contain his scores from the first and second innings, respectively. This would be a paired test since each row in the data would correspond to the same match.What would be the null hypothesis in this case?H₀: μ₂ - μ₁ = 0H₀: μ₂ - μ₁ ≥ 0H₀: μ₂ - μ₁ ≤ 0H₀: μ₁ - μ₂ ≠ 0
