For the project, you will have to: Collect and organize a sample of 30 items of data from a source you find relevant. Some examples: Sports (top HR hitters, rushing leaders, point scorers, etc.) Weather (average daily temperature for a month, max hurricane wind speed, etc.) Business (top-grossing movies, highest-paid athletes, record sales, etc.) Demographics (age, height, weight, etc.) Find the mean, median, mode, and mid-range for your date. Find the variance, standard deviation, and range for your data. Find the five-number summary and determine (mathematically) if there are any outliers. Construct a 95% confidence interval for the mean of your data.       You are allowed to use the calculator for the calculations but you must provide me with the 30 data values you obtain in a neat, organized manner, preferably in a spreadsheet. Also, be sure to provide the source of your data. When you provide the answers to the questions above please use the correct symbols and notation.…

The accompanying table shows trade deficits for a certain country (in billions of dollars) to 19 other countries for a recent year. Complete parts (a) through (c) below. Click the icon to view the table of exports from a country to other countries. (a) Find the mean and median of the trade deficits. The mean of the trade deficits is $ billion. (Round to two decimal places as needed.) The median of the trade deficits is $ billion. (Type an integer or a decimal. Do not round.) (b) Find the mean and the median of the trade deficits without trade deficit to country A. Which measure of central tendency, the mean or the median, was affected more by the elimination of trade deficits to country A? The mean of the trade deficits is $ billion. (Round to two decimal places as needed.) The median of the trade deficits is $ billion. (Type an integer or a decimal. Do not round.) Which measure of central tendency was affected more by the elimination of trade deficits to Country A? OA. The mean was…
