Rebecca is a real estate agent who would like to find evidence supporting the claim that the population mean market value of hou
nydimaria [60]

Answer:

Option C) There are enough evidence that at significance level of 0.05 to support the claim that the the population mean market value of houses in the neighborhood where she works is greater than $250,000.

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = $250,000

Sample mean, \bar{x} = $259,860

Sample size, n = 35

Alpha, α = 0.05

Sample standard deviation, σ = $24.922

First, we design the null and the alternate hypothesis

H_{0}: \mu = 250,000\text{ dollars}\\H_A: \mu > 250,000\text{ dollars}

We use One-tailed t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} } = 2.34

0.01 < \text{ p-value }< 0.025

Since the p-value is less than the significance level, we fail to accept the null hypothesis.

There are enough evidence that at significance level of 0.05 to support the claim that the the population mean market value of houses in the neighborhood where she works is greater than $250,000.
