Question

Hypothesis Testing -Age of Oldest Person: The SUNY Oneonta Office of Old Folks maintains that the mean age of the oldest person known to current undergraduate students (aged 18-25 yrs.) is 97 years. Recently a sample of 74, 18-25 yr. old students identified the age of the oldest person they knew. The mean age was 93.04 yrs. with a standard deviation of 7.10 yrs., a median age of 93.00 yrs., a range of 73 to 112 yrs., and a skew for the data of .22. Do the current data support the Office of Old Folks’ mean? For your answer, SELECT THE APPROPRIATE HYPOTHESES.

	A.	H₀: µ = 93.04 yrs. H_a: µ ≠ 93.04 yrs.
	B.	H₀: µ = 97.00 yrs. H_a: µ ≠ 97.00 yrs.
	C.	H₀: µ = 93.04 yrs. H_a: µ > 93.04 yrs.
	D.	H₀: µ = 97.00 yrs. H_a: µ > 97.00 yrs.
	E.	H₀: µ = 93.04 yrs. H_a: µ < 93.04 yrs.
	F.	H₀: µ = 97.00 yrs. H_a: µ < 97.00 yr
