Webb12 apr. 2024 · Looking at the z-table, that corresponds to a Z-score of 1.645. Since it is on the left, it is with a minus sign. Accept or Reject. Now, when calculating our test statistic Z, if we get a value lower than -1.645, we would reject the null hypothesis. We do that because we have statistical evidence that the data scientist salary is less than ... WebbOur observed value of z is 2.13 which is greater than the critical value of 1.64. We therefore reject H0. Equivalently, we can calculate the p-value for our observed mean and compare it to alpha. For this one-tailed test, the p-value is the area under the normal distribution above our observed value of z. From the z-table: z Area between mean and z
