   21 sie 2024 · By conducting a hypothesis test, we can try to prove that the null hypothesis is false against the alternative hypothesis. For example, suppose we have the data(6,7,8,9,5,4,10,4) from A7:A14. Then, to calculate the one-tailed probability value of a Z.TEST for the data with a hypothesized population mean of 4, we will use the following formula:
