Test the
hypotheses H0:μ≤420 vs. H0:μ>420 with
a significance level of 0.05, given that σ=28 and that a
sample of size 25, taken from a normal distribution, produced a
sample mean of 426.8. Which of the following is the
correct p-value and conclusion?
A. p=0.1180, reject H0
B. p=0.1123, reject H0
C. p=0.1180, do not reject H0
D. p=0.1123, do not reject H0
Test the hypotheses H0:μ≤420 vs. H0:μ>420 with a significance level of 0.05, given that σ=28 and that a sample of size 2
