Given μ=400 and σ=50, compute the z score for an observation of x^i=463 Round your final answer to three decimal places.
Assume a normal distribution with μ = 0 and σ = 1, find the z-score(s) for each statement below: a) the area is 0.8 to the left of z b) the area is 0.11 to the right of z c) the middle area is 0.45 between −z and z ;
Calculate the standard score of the given X value, X=89.7, where μ=88.2 and σ=89.4 and indicate on the curve where z will be located. Round the standard score to two decimal places.
use the standard normal table to find the z-score that corresponds to the given percentile . if the area is not in the table use the entry closest to the area if its halfwy between the two entries, use the z score halfway between the corresponding z-score . p20
30 Use the standard normal table to find the z-score that corresponds to the given percentile. If the area is not in the table, use the entry closest to the area. If the area is halfway between twoentries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score.

Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score.0.049The cumulative area corresponds to the z-score of _______
Consider a normal population with μ = 37 and σ = 4.3. Calculate the z-score for an x of 48.5 from a sample of size 11. (Give your answer correct to two decimal places.) You may need to use the appropriate table in Appendix B to answer this question.
