The test statistic used for this procedure is two sample t-test.
What is test static?
A statistic employed in statistical hypothesis testing is known as a test statistic. A hypothesis test is often described in terms of a test statistic, which can be thought of as a numerical summary of a data set that distills the information into a single value that can be used to conduct the test.
Test Statistic for The Procedure
It is given that mean of the differences = 1.33
And, the standard deviation of the differences, standard error = 2.90
The test static formula is given as,
t = (estimate - hypothized value) / standard error
Here, t is the test statistic, and estimate is the mean of the differences.
Since it is given that all conditions are met, the hypothized value = 0
Substituting substituting estimate = 1.33 and standard error = 2.90 in the test statistic formula, we get,
t = (1.33-0)/2.90
t = 0.458
