Finding probability from z score
WebSep 13, 2024 · Finding z = 1.53. Here, a Z-score of 1.53 corresponds to a value of 0.9370 in the table. This means that the area under the curve to the LEFT of 1.53 is 0.9370. Said another way, 93.7% of the data ... WebAug 6, 2024 · To find the p-value associated with a z-score in R, we can use the pnorm () function, which uses the following syntax: pnorm (q, mean = 0, sd = 1, lower.tail = TRUE) where: q: The z-score mean: The mean of the normal distribution. Default is 0. sd: The standard deviation of the normal distribution. Default is 1.
Finding probability from z score
Did you know?
WebThe cumulative probability for a value equals the cumulative probability for that value's z-score. Here, probability speed less than or equal 73 mph = probability z-score less than or equal 1.60. How did we arrive at this z-score? Example . In our vehicle speed example, the standardized scores for 73 mph is \(z=\frac{73-65}{5}=1.60\).
