6.3: Finding Probabilities for the Normal Distribution
WebZ.TEST represents the probability that the sample mean would be greater than the observed value AVERAGE (array), when the underlying population mean is μ0. From the symmetry of the Normal distribution, if AVERAGE (array) < x, Z.TEST will return a value greater than 0.5. The following Excel formula can be used to calculate the two-tailed ... WebMar 18, 2024 · Let's consult a z-table, such as this one.We only need one number: when z = -2.58 and we can do some math to get the final answer. The table says that the P(#z < -2.58#) = .0049 or 0.49%.We also know that the normal curve is symmetric, meaning that any area can be flipped (i.e. #P(z < z_0) = P(z > -z_0)# and visa versa). That means that … WebMar 30, 2024 · The probability is the area under the curve from 0 to the probability value. The area under the full curve is. From the z-tables: P (Z < 1.96) = .9750.
