Question: In a population, = 100 and x = 25. A sample (N = 150) has X = 102. Using two tails of the sampling

In a population, µ = 100 and σx = 25. A sample (N = 150) has X = 102. Using two tails of the sampling and the .05 criterion:
(a) What is the critical value?
(b) Is this sample in the region of rejection? How do you know?
(c) What does this indicate about the likelihood of this sample occurring in this population?
(d) What should we conclude about the sample?
