Question9 1 pts The mean area 11 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. In order to investigate this suspicion, the group hires an engineer to measure a sample of apartments. The appropriate null and alternative hypotheses, Ho and Ha for are (where represents the mean square footage of the new apartments) O Ho: -1100 and Hai 1100. 0 Hop-1100 and Hai +1 100. Ho= 1100 and Ha·p> 1100. O The hypotheses cannot be specified without knowing the size of the sample used by the engineer

Explanation / Answer

The null hypothesis is that of equality and therefore it should be =1100 but the alternate hypothesis is one sided here which is <1100. thus answer is B
