A random sample of n observations is selected from a normal population to test the null hypothesis
Question:
A random sample of n observations is selected from a normal population to test the null hypothesis that σ2 = 25. Specify the rejection region for each of the following combinations of Ha, α, and n:
a. Ha: σ2 ≠ 25; α = .05; n = 16
b. Ha: σ2 > 25; α = .01; n = 23
c. Ha: σ2 > 25; α = .10; n = 15
d. Ha: σ2 < 25; α = .01; n = 13
e. Ha: σ2 ≠ 25; α = .10; n = 7
f. Ha: σ2 < 25; α = .05; n = 25

I cleared my JEE Advanced in 2018 and got ranked 73 among 1.5 million students and if you calculate it is above 99.99 percentile. After the JEE Advanced, I am teaching juniors of class 11-12th in the last two summers and they were very satisfied with my teaching skills and my unique way of explaining difficult concepts in a simple way. I have also taught my younger sister and her friends for 3 years. I have a great style of teaching and also a good command on my subjects which forms a deadly combination and gives me an upper hand on other tutors who either lack teaching style or solving ability.
