In a hypothesis test, an extreme z-score value, like z = +3 , or z = +4, ________ is probably in the critical region means that you should probably reject the H0 Both of the above options are correct

Step 1
An extreme z-score value, like $z = +3$ or $z = +4$, means that the observed value is far from the mean, assuming the null hypothesis ($H_0$) is true. Show more…

Standard Normal Distribution Mean = 0.0 Standard Deviation = 1.0 .5000 .2500 .2500 -0.67 0.67 The critical region is The z-score boundaries for an alpha level α = .001 are: z = 2.58 and z = -2.58 z = 3.29 and z = -3.29 z = 1.96 and z = -1.96 Suppose that the calculated z statistic for a particular hypothesis test is 4.08 and the alpha is .001. This z statistic is the critical region. Therefore, the researcher reject the null hypothesis, and she conclude the alternative hypothesis is probably correct.

The critical boundaries for a hypothesis test are z = +1.96 and -1.96. If the z-score for the sample data is z = -1.90, then what is the correct statistical decision? - reject alternative hypothesis H1 - fail to reject null hypothesis H0 - fail to reject alternative hypothesis H1 - reject null hypothesis H0
