WebApr 11, 2024 · The Z-table is a comprehensive reference tool that allows users to quickly determine the probability of obtaining a specific value or range of values from a normal distribution. The table is organized by Z-score, which is a measure of the number of standard deviations from the mean that a given value falls. WebFinal answer. Suppose Z follows the standard normal distribution. Use the calculator provided, or this table, to determine the value of c so that the following is true. P (−0.77 ≤ Z ≤ c)= 0.7384 Carry your intermediate computations to at least four decimal places. Round your answer to two decimal places.

WebFeb 16, 2024 · A z-table, also called the standards common table, is a arithmetical graphic such allows about toward recognize the share of values below (to the left) a z-score in a … WebFor scientific calculators, you can calculate the confidence level using the normalcdf function (the lower and upper boundaries will be negative and positive z*, respectively). You can also find z* by using the Inverse Normal (invNorm) function. Try searching your calculator on the Internet to check if you have these functions. WebZ-Test is usually used to conduct a hypothesis test when the sample size is greater than 30. This is because of the central limit theorem where when the sample gets larger, the distributed data graph starts resembling a bell curve and is considered to be distributed normally.
