The mean area of the several thousand apartments in a new development by a certain builder is advertised to be 1100 square feet. A tenant group thinks this is inaccurate and suspects that the actual average area is less than 1100 square feet. To investigate this suspicion, the group hires an engineer to measure a sample of apartments. The appropriate hypotheses to test the tenants group claim about μ are: Hou 1100 and Ha: 1100 Hoμ = 1100 and Ha: < 1100 Hoμ = 1100 and Ha: > 1100 μµ - The hypotheses cannot be specified without knowing the size of the sample used by the engineer.
