Rosetta wants to estimate the percentage of people who rent their home. She surveys 250 individuals and finds that 48 rent their home. Use a calculator to find the confidence interval for the population proportion with a 90% confidence level. 0.10 0.05 0.025 0.01 0.005 1.282 1.645 1.960 2.326 2.576

Step-by-step explanation:

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:

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
