Answer:

The lower bound of the 95% confidence interval for the mean sale time for all homes in the neighborhood is of 160 days.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1 - 0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1 - \alpha$ .

That is z with a pvalue of $1 - 0.025 = 0.975$ , so Z = 1.96.

Now, find the margin of error M as such

$M = z\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96\frac{72}{\sqrt{22}} = 30$

The lower end of the interval is the sample mean subtracted by M. So it is 190 - 30 = 160 days

The lower bound of the 95% confidence interval for the mean sale time for all homes in the neighborhood is of 160 days.
