4. A fast food outlet claims that the mean waiting time in line is at most 2.5 minutes. A former manager of one of these restaurants believes the wait time is more than 2.5 minutes. For a sample of n = 50 visits to these outlets, the mean wait was 2.7 minutes with a deviation of 1.5 minutes. Which of the following represent the null and alternative hypotheses necessary to test the fast food outlet's claim?  Also, state the final conclusion if we decide that we will not reject the null hypothesis.
A. H0: μ = 2.5 vs. Ha: μ ≠ 2.5; The data supports the former manager's claim.
B. H0: μ ≥ 2.5 vs. Ha: μ < 2.5; The data supports the former manager's claim. 
C. H0: μ ≥ 2.5 vs. Ha: μ < 2.5; The data does not support the former manager's claim.
D. H0: μ ≤ 2.5 vs. Ha: μ > 2.5; The data does not support the former manager's claim.
E. H0: μ ≤ 2.5 vs. Ha: μ > 2.5; The data supports the former manager's claim.
F. None of these
