Assume a population of 40, 45, 47, and 53. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the sixteen different samples.   Find the Sample Median and Probability of each grouping, and then compare the population median to the mean of the sample medians. Choose the correct answer below.     A. The population median is equal to half of the mean of the sample medians.   B. The population median is equal to double the mean of the sample medians.   C. The population median is equal to the mean of the sample medians.   D. The population median is not equal to the mean of the sample medians (it is also not half or double the mean of the sample medians).

Find the mean, median and mode of the given sample. How would the mean, and median change if the highest salar is omitted? $250,00, $300,000, $350147, $232,425, $360,000, $1,231,421, $810,000, $229,000

Use the magnitudes​ (Richter scale) of the earthquakes listed in the data set below. Find the mean and median of this data set. Is the magnitude of an earthquake measuring 7.0 on the Richter scale an outlier​ (data value that is very far away from the​ others) when considered in the context of the sample data given in this data​ set? Explain. a. Find the mean and median of the data set using a calculator or similar data analysis technology. The mean of the data set is ​(Round to three decimal places as​ needed.) b. The median of the data set is ​(Round to three decimal places as​ needed.)

The tuition and fees (in thousands of dollars) for the top 14 universities in a recent year are listed below. Find the mean, median, and mode of the data, if possible. If any of these measures cannot be found or a measure does not represent the center of the data, explain why. 42 44 35 42 45 44 46 44 42 44 47 44 45 Q 39 C Find the mean cost. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The mean cost is (Round to one decimal place as needed.) OB. There is no mean cost. Does the mean represent the center of the data? O A. The mean represents the center. O B. The mean does not represent the center because it is not a data value. O C. The mean does not represent the center because it is the largest data value. O D. The mean does not represent the center because it is the smallest data value. O E. There is no mean cost. Find the median cost. Select the correct choice below and, if necessary, fill in the answer box to complete your…
