The results of sampling independence populations:

sample 1 from population 1

a) mean 1000

b) sample standard deviation 400

c) sample size 50

sample 2 from population 2

a) mean 1250

b) sample standard deviation 500

c) sample size 75

Test the HO: population1 mean = population2 mean at α - 0.01. HA: population1 mean ≠

population2 mean. This is a two-tailed test with both a negative lower critical value and a

positive upper critical value. Separate variances is assumed

Select from the following answer:

a) Pvalue 0.9988. HO not rejected. Conclude difference of means = 0 plausible

b) Pvalue 0.0012. HO rejected. Conclude difference of means ≠ 0.

c) Pvalue 0.0025. HO rejected. Conclude difference of means ≠ 0.
