AJ DAVIS is a department store chain, which has many credit customers and wants to find out more information about these customers. A sample of 50 credit customers is selected with data collected on the following five variables:

The Written Report must be five pages and graphically display the statistical data developed for three comparable cities, counties, or states. It must incorporate national statistics for comparison. Your assessment may be in bullet or paragraph format below the graphic display.

The sales data were obtained for a new oceanside condominium complex consisting of two adjacent and connected eight-floor buildings. The complex contains over 200 units of equal size (approximately 500 square feet each). The

e.) Find a 95% confidence interval for the proportion who stay with D&Y for at least 3 years but this time with starting salaries above the median.

To begin the statistical analysis of the data provided, we need to present the statistical description of it, take a general look at the means and medians for each sector and test the normal distribution of the data to see if we can undertake any further test.

To calculate the mean I added up the sum of days to sell and divided by 18. The mean is 203,188.89, which mean the average of the listed price. The median was calculated by listing the numbers in numerical order from lowest to highest and located the number in the middle of 203,500. The median represents the middle number of the days that it took to sell the condominiums. After calculating the median I located the minimum and maximum based the lowest and highest data, which are 135,500 and 292,500. These represent the range of the sale price. Lastly, I used the formula to get the standard deviation of 43,891.72, which measures the variability.

a) Develop a 99 percent confidence interval for the mean selling price of the home.

The data for the second test to be conducted by our group consists of lot sizes of the residential properties that are up for sale in Toronto and Vancouver.
