The Bureau of Labor Statistics (BLS) is the main fact-finding agency of the US government in the fields of labor economics and s
tatistics. Data from the Current Population Survey (CPS), conducted by the BLS and the Census Bureau, have been used to indicate a downward trend in retirement age. [Source: Gendell, M. (October 2001). Retirement age declines again in the 1990s. Monthly Labor Review, 124(10), 12-21.] The following DataView tool displays a hypothetical data set consisting of annual income (as measured in thousands of dollars) and age of retirement for 100 retirees.
Use the tool to view the histogram of the retirement ages of the retirees, and answer the questions that follow. (Hint: Click either one of the Variable sliding panels in the bottom left-hand corner of the tool screen. Click the downward-pointing arrow next to Select Variable, and select the variable Retirement Age. Click the Histogram button in the middle of the left-hand side of the screen to view a histogram of its distribution.)

___________of the distribution of the retirement ages extends farther than the other tail. Therefore, this distribution is ________
Use the tool to obtain the mean and median of the retirees' retirement ages. (Hint: On the Variable sliding panel for the variable Retirement Age, click the Statistics button to view computed statistics for the variable.)
The mean is________ y, and the median is________. The mean is ________ than the median.
Use the tool to view the histogram of the incomes of the retirees. (Hint: Click a Variable sliding panel in the bottom left-hand corner of the tool screen. Click the downward-pointing arrow next to Select Variable, and select the variable Income. Again, click the Histogram button.)
_________ of the distribution of the incomes extends farther than the other tail. Therefore, this distribution is ________
Use the tool to obtain the mean and median of the incomes. (Hint: Select the Variable sliding panel for the variable Income, and click the Statistics button.)
The mean is _______ , and the median is _______ V. The mean is than the median. When the distribution is symmetrical, the mean is the median. When the distribution is positively skewed, the mean is usually ________ the median. When the distribution is negatively skewed, the mean is usually ______ the median. than the median. Therefore the is the preferred
The presence of extremely large or small values in the data affects the mean ________ measure of central tendency when the distribution is skewed.
So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6. <span />
Hello, Here is the formula to find the area of the trapezoid: A=1/2(b1+b2)×h Where b1 represent big base b2 represent small base and h represent height Now, we just need to replace the number to get the final answer: A=1/2(16.8+6.9)×2 A=1/2(23.7)×2 A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!
