Population variance calculator with steps
WebStep 3: Add up all of the squared differences from Step 2: (16-9) 2 + (11-9) 2 + (9-9) 2 + (8-9) 2 + (1-9) 2 = 118. Step 4: Divide Step 3 by the number of items. 118/5 gives a population … WebSolve. Example 1 • Example 2. The first step in hypothesis testing is to calculate the test statistic. The formula for the test statistic depends on whether the population standard deviation (σ) is known or unknown. If σ is known, our hypothesis test is known as a z test and we use the z distribution. If σ is unknown, our hypothesis test ...
