find the p value for the indicated hypothesis test with the given standardized test statistics, z. decide wheather to reject h0 for the given level of significance A. two tailed test with test statistics z=-1.58 and a= 0.07
Thank you for the opportunity to help you with your question!
. In a
2-tailed test it is necessary to divide alpha by 2, and there are 2
corresponding critical values. If alpha is specified as -1.58, then
dividing it by 2 we obtain -0.79 for each tail. At the lower tail, the
critical z-value corresponds with P(Z < z) = 0.07. Therefore, z =
-1.751. At the upper tail, the critical z-value corresponds with P(Z
< z) = 0.96. Therefore, z = 1.751.
Please let me know if you need any clarification. I'm always happy to answer your questions.
