WebSep 4, 2024 · Make a decision based on the p-value for the given value of σ (significance) To find the p-value using z-score. Situation 1: If the sample mean is on the right side of the distribution mean, z-value= +3.02, then from Z-table, we can find the value = 0.9987 Now, For one-tailed test → p = 1–0.9987 = 0.0013 WebP(Σx ≥ 1,600) = normalcdf(1600,E99,1514.10,63) = 0.0864; P(Σx ≤ 1,595) = normalcdf(-E99,1595,1514.10,63) = 0.9005. This means that there is a 90% chance that the sum of …
WebX ~ B(n, p) where n = 300 and p = 0.53. Since np > 5 and nq > 5, use the normal approximation to the binomial. The formulas for the mean and standard deviation are μ = np and σ = n p q n p q. The mean is 159 and the standard deviation is 8.6447. The random variable for the normal distribution is Y. Y ~ N(159, 8.6447). WebHere's the same formula written with symbols: z=\dfrac {x-\mu} {\sigma} z = σx − μ Here are some important facts about z-scores: A positive z-score says the data point is above average. A negative z-score says the data point is below average. A z-score close to 0 0 says the data point is close to average.
