**Final Exam Fall B 2013 MAT 154 Practice Exam MULTIPLE**

Find the z - score corresponding to the given value and use the z - score to determine whether the value is unusual. Consider a score to be unusual if its z - score is less than - 2.00 or greater than 2.00.... In the offline version, you use a z score table to look up the critical value for the test based on your desired level of alpha. Remember to adjust the alpha value based on wether you are doing a single-tailed test or two tailed test. In this case, we can simply split the value of alpha in two since the standard normal distsribution is symmetric about its axis. From there, finding the critical

**if a= 0.01 then for a left-tailed test the critical value**

How do I find the critical value for the t-score if we want to say something with 95% confidence and we have a two-tailed test? Referring to the left-tailed normal distribution table, what should I do if the z-score is greater than 3?... 15/07/2008 · Best Answer: the critical value is z such that P( Z < z) = 0.01 z = -2.326348 First I'll let you in on the answer, followed up by an explanation to help you on your way. Your answer is; the critical value of alpha 0.01 for a left tailed test is 2.33 *****... FOR A ONE-TAILED TEST: Level of significance or the z critical value of

**Solved Find The Critical Point(s) For The Following A) Z**

If an obtained mean corresponds to a z score whose absolute value is greater than the absolute value of the critical z score, then the null hypothesis should be rejected. The critical value depends on (a) the alpha level and (b) whether we’re using a one-tailed or two-tailed test.... the set of scores for one sample is uncorrelated with the scores in the other sample When testing the means of independent samples, the null hypothesis is BEST thought of as... the mean of the population 1 is equal to the mean of population 2

**if a= 0.01 then for a left-tailed test the critical value**

The mean score for males is 98 and the mean score for females is 100. We use an independent groups t-test and find that the difference is significant at the .001 level. The big question is, "So what?". The difference between 98 and 100 on an IQ test is a very small difference...so small, in fact, that it's …... Find the z - score corresponding to the given value and use the z - score to determine whether the value is unusual. Consider a score to be unusual if its z - score is less than - 2.00 or greater than 2.00.

- One- and two-tailed tests. Jump to navigation Jump to search. A A two-tailed test is appropriate if the estimated value may be more than or less than the reference value, for example, whether a test taker may score above or below the historical average. A one-tailed test is appropriate if the estimated value may depart from the reference value in only one direction, for example, whether a
