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 26552655 ft 22 with a standard deviation of 205205 ft 22 . 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 3636 homes in the neighborhood and finds the average home size to be 24652465 ft 22 . which of the following are the correct null and alternative hypotheses? null hypothesis : ⎯⎯⎯=2465h0: x¯=2465 ft 22 : < 2655h0: μ< 2655 ft 22 : =2655h0: μ=2655 ft 22 : ⎯⎯⎯< 2655h0: x¯< 2655 ft 22 : ⎯⎯⎯=2655h0: x¯=2655 ft 22 : =2465h0: μ=2465 ft 22 alternative hypothesis : ⎯⎯⎯≠2655h1: x¯≠2655 ft 22 : < 2655h1: μ< 2655 ft 22 : ≠2655h1: μ≠2655 ft 22 : < 2465h1: μ< 2465 ft 22 : ⎯⎯⎯< 2655h1: x¯< 2655 ft 22 : ⎯⎯⎯< 2465h1: x¯< 2465 ft 2
