Rebecca is a real estate agent who would like to find evidence supporting the claim that the population mean market value of houses in the neighborhood where she works is greater than $250,000. To test the claim, she randomly selects 35 houses in the neighborhood and finds that the sample mean market value is $259,860 with a sample standard deviation of $24,922. The test statistic t for a hypothesis test of Ho : μ = 250,000 versus Ha : μ 〉 250,000 is t 2.34 , which has 34 degrees of freedom. If 0.01

Question
Rebecca is a real estate agent who would like to find evidence supporting the claim that the population mean market value of houses in the neighborhood where she works is greater than $250,000. To test the claim, she randomly selects 35 houses in the neighborhood and finds that the sample mean market value is $259,860 with a sample standard deviation of $24,922. The test statistic t for a hypothesis test of Ho : μ = 250,000 versus Ha : μ 〉 250,000 is t 2.34 , which has 34 degrees of freedom. If 0.01 <p-value< 0.025 and the level of significance is α-0.05, which of the following statements are accurate for this hypothesis test to evaluate the claim that the true population mean market value of houses in the neighborhood where she works is greater than $250,000? Select all that apply: O Fail to reject the null hypothesis that the true population mean market value of houses in the neighborhood where Rebecca works is equal to $250,000 Reject the null hypothesis that the true population mean market value of houses in the neighborhood where Rebecca works is equal to $250,000 There is enough evidence at the a 0.05 level of significance to support the claim that the true population mean market value of houses in the neighborhood where Rebecca works is greater than $250,000. There is not enough evidence at the α-0.05 level of significance to suggest that the true population mean market value of houses in the neighborhood where Rebecca works is not equal to $250,000.
