Conduct the following test at the Alpha=0.05 level of significance by determining ​(a) the null and alternative​ hypotheses, ​(b) the test​ statistic, and​ (c) the​ P-value. Assume that the samples were obtained independently using simple random sampling.

Test whether p 1 not equals p 2. Sample data are x 1 = 28, n 1 = 254, and x 2 = 36, n 2 = 302. Show how to solve using StatCrunch.

Answer #1

Go to StatCrunch --> Stat --> Proportion Stats --> Two Sample --> With Summary

Put the inputs like below:

You will get the below results after clicking on "compute":

Hence,

Test statistic = -0.33

P - value = 0.741
