WebNov 27, 2024 · z-value = (105–100)÷ (15÷√7.5) = 2.89. This value 2.89 is called the test statistic. This takes us to our last step. 5. Draw a conclusion. So, if you look at the curve, the value of 2.89 will definitely lie on the red area towards the right of the curve because the critical value of 1.96 is less than 2.89.
