Find the probability p −1.86 ≤ z ≤ 0
WebNov 5, 2024 · Step 2: Find the p value To find the probability of your sample mean z score of 2.24 or less occurring, you use the z table to find the value at the intersection of row 2.2 and column +0.04. The table tells you that the area under the curve up to or below your z score is 0.9874. WebFeb 16, 2024 · To find the value of z0 such that P (−z0≤z≤z0) = 0.8026, we can use the symmetry property of the standard normal distribution. Since the probability is split equally on both sides of the mean, we can find the z- score that corresponds to a probability of (1-0.8026)/2 = 0.0987 on the left tail. Looking up this value, we get z ≈ -1.29.
