When a z-score is NOT in the region of rejection, we should ______.Choose onereject the idea that random chance produced a sample the represents the population poorlyconclude with the idea that the sample scores and the raw score population are similar enough to be called identicalnot reject the idea that the sample represents the raw score populationreject the idea that the sample represents the raw score population

A z-score is most affected by the ______.Choose onemedianmodestandard deviationrange

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?Group of answer choicesFail to reject H1Reject H1Fail to reject H0Reject H0

A z score is a standard score with a:Choose oneM = 2 and SD = -1M = 0 and SD = 0M = 0 and SD = 1M = 1 and SD = 0

A standardized value, commonly called a z-score relies on the values of Group of answer choicessample standard deviation and the meanmedianmodeaverage distribution

A researcher conducts a hypothesis test to evaluate the effect of a treatment that is expected to increase scores. The hypothesis test produces a z-score of z = 2.37. If the researcher is using a one-tailed test, what is the correct statistical decision?​Group of answer choices​Reject the null hypothesis with α = .05 but not with α = .01.​This cannot be answered without additional information.​Reject the null hypothesis with either α = .05 or α = .01.​Fail to reject the null hypothesis with either α = .05 or α = .01.
