Suppose Rachel is searching for a new home. A report on the neighborhood she is interested in states that the average home size in the neighborhood is 2615 ft 2 with a standard deviation of 185 ft 2 . Rachel thinks that this report is inaccurate and that homes in this neighborhood are smaller than reported. She investigates the records of a random sample of 36 homes in the neighborhood and finds the average home size to be 2415 ft 2 . Which of the following are the correct null and alternative hypotheses? Null hypothesis H0:µ<2615 ft 2 H0:µ=2415 ft 2 H0:x⎯⎯⎯=2415 ft 2 H0:x⎯⎯⎯<2615 ft 2 H0:µ=2615 ft 2 H0:x⎯⎯⎯=2615 ft 2 Alternative hypothesis H1:x⎯⎯⎯≠2615 ft 2 H1:µ≠2615 ft 2 H1:x⎯⎯⎯<2415 ft 2 H1:x⎯⎯⎯<2615 ft 2 H1:µ<2615 ft 2 H1:µ<2415 ft
