QUESTION 1 Suppose the cutoff z score on the nuli distribution is Zcrit = +1.35. You could reject the null hypothesis if the sample z score was 02.16
For each give (a) the Z-Score cutoff (or cutoffs) on the comparison distribution at which the Null Hypothesis should be rejected, (b) the Z-score on the comparison distribution for the sample score, and (c) your conclusion. Assume that all Populations are normally distributed. Study-M-SD-Sample Score-P-Tails of Test A-100.0-10.0-80-.05-1(low prediction) B-100.0-20.0-80-.01-2 C-74.3-11.8-80-.01-2 D-76.9-1.2-80-.05-1(low prediction) E-88.1-12.7-80-.05-2
Find the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.05 significance level. Is the alternative hypothesis supported? H0: μ=17.5 meters, Ha: μ≠17.5 meters, n=49, x overbar =16.9 meters, σ =1.5 meters The value of the standard score is ____. (Round to two decimal places) Find the standard Z score ______. (Round to two decimal places) Is the hypothesis test one tailed for two-tailed? The hypothesis test is ____________ While technology or...
if the zobt is greater than the z critical, what can i assume within this data set? A.Since zobt > zcrit, we have proven the alternative hypothesis. B.Since zobt > zcrit, we fail to reject the null hypothesis. C.since zobt > zcrit, we reject the null hypothesis.
If the cutoff for a one-tailed z test is -1.65, choose which of the following z scores would cause you to reject the null hypothesis: a)-1.2 b)-3.5 c)-2.3 d)2.5 e)-1.96 f)1.5 g) 0
Question 22 3 pts Suppose you are interested in testing a null hypothesis and the p-value associated with the test statistic is 0.004. As a result, you should o reject the null hypothesis at the 5-percent level of significance, but not at the 1- percent level of significance. do not reject the null hypothesis at the 5-percent level of significance, but do reject the null at the 1-percent level of significance. o do not reject the null hypothesis at the...
In a hypothesis test, an extreme z-score value, like z=+3 or z=+4, then a. is probably in the critical region b. means that you should probably reject the null hypothesis
Find the value of the standard score, z, and determine whether to reject the null hypothesis at a 0.01 significance level. Is the alternative hypothesis supported? Upper H 0 : mu equals18.6meters, Upper H Subscript a : mu not equals18.6meters, nequals 121 , x overbar equals19.3meters, sigma equals1.1meters
