16. What is the Pvalue?

Question

A 1-tail, normal distribution of n = 64, alpha risk = 10%.
Sample mean = 206;
Ho: Population mean is no more than 202
Sample standard deviation = 16.
What is the Pvalue?

Answer 1

t = (x-µ)/(s/√n) = (206-202)/(16/√64) = 2

d.f. = 64-1=63

p-value = 1-0.975 = 0.025
