To test H0: μ= 100 versus H1: μ ≠ 100
To test H0: μ= 100 versus H1: μ ≠ 100, a simple random sample size of n = 16 is obtained from a population that is known to be normally distributed.
(a) x̅ = 104.7 and s = 8.4. compute the test statistic.
Homework Answers
solution:-
given that n = 16 and µ = 100
(a) if x = 104.7 , s = 8.4
test statistic t = (x-µ)/(s/sqrt(n))
t = (104.7-100)/(8.4/sqrt(16))
t = 2.238
