The mean area μ of the several thousand apartments in a new development by a certain builder is advertised to be 1250 square feet. A tenant group thinks this is inaccurate and suspects that the average is actually less than 1250 square feet. Apartments are randomly selected and carefully measured. The appropriate null and alternative hypotheses relevant to this example are
A. H0: μ = 1250 and Ha: μ 1250.
B. H0: μ = 1250 and Ha: μ > 1250.
C. H0: μ = 1250 and Ha: μ < 1250.
D. unable to be determined without knowing how many apartments were sampled.
