Best Answer

You either look it up in a table of z scores or you can use a calculator such as the TI8 and use normalcdf.

What is the 2 sided p value associated with a z score of 1.54?

How do you find p value with test statistic and critical value?

Normally you would find the critical value when given the p value and the test statistic.


Can a negative z score be greater than a positive z score?

Assume the z-score is relative to zero score. In simple terms, assume that we have 0 < z < z0, where z0 is the arbitrary value. Then, a negative z-score can be greater than a positive z-score (yes). How? Determine the probability of P(-2 < z < 0) and P(0 < z < 1). Then, by checking the z-value table, you should get: P(-2 < z < 0) ≈ 0.47725 P(0 < z < 1) ≈ 0.341345


How do you find the number z such that the proportion of observations that are less than z in a standard Normal distribution is 0.7?

You will need to use tables of z-score or a z-score calculator. You cannot derive the value analytically.The required z-score is 0.524401


Define p-value vs - z score?

The p-value is the probability of any event or the level of significance for any statistical test. The z-score is a transformation applied to a Random Variable with any Normal distribution to the Standard Normal distribution.


What is the rejection region and how does it relate to Z score and the p value?

The rejection region for a hypothesis is the set of values such that if the null hypothesis is true, then the probability of observing a value for the test statistic (the z-score) for a random variable that may be assumed to have a Normal distribution, is at least as great as the value actually observed is less than by chance. The latter is an arbitrarily selected value called the p-value - often 5% or 1%.Note that z-scores may be used only if the random variable is approximately Normally distributed - not otherwise.


Is probability and p value same?

No. p-values are probabilities but they are not the only ones.


How is z score and p value related?

The z-score is a statistical test of significance to help you determine if you should accept or reject the null-hypothesis; whereas the p-value gives you the probability that you were wrong to reject the null-hypothesis. (The null-hypothesis proposes that NO statistical significance exists in a set of observations).


What is the indicated z score for 0.9693?

The one-tailed z-value is: P(Z < z) = 0.9693 => z = 1.8706


Let the function f x be defined by f x 2x-3 If p is real number what is one possible value of p for which f p p?

The only possible value of p is 3.


The random variable z is the normal score find p -1.31z0.31?

Prob (-1.31 < z < 0.31) = 0.5266


How do you find a P-value?

You need to perform the Z-test on the calculator to find the P-value. The data should be entered by pressing "STAT". Here is a link to guide you; http://calculator.maconstate.edu/mean_test_z/index.html
