Information given
number of people who rent their home
represent the sample size
represent the proportion of people who rent their home
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by and . And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
4.5w = 5.1w - 30
4.5w - 5.1w = -30
-0.6w =-30
Divide both sides by -0.6
-0.6w/-0.6 = -30/-0.6
<span>w = 50
