Answer #1

Standard deviation is never negative. Standard deviation is sensitive to outliers. Standard deviation is nothing but the spread of the data. A single outlier can raise the standard deviation.

Thus we remove the outliers it results the decrease the standard deviation.

Therefore, if we remove outliers standard deviation decrease

Question2: The following function is supposed to receive a list of numbers and a number as the input parameters. The function finds all occurrences of number inside the list and removes them from the list and eventually returns the results. Do you think this function will work as expected? If yes, please mention and if no, please fix it. def function(listOfNumbers, number): for i in range(len(listOfNumbers)): if listOfNumbers[i]==number: listOfNumbers.remove(number) return listOfNumbers newList = function([3,4,1,3,4,7,8,1,2,3,4,6,8], 3) print("After removing the occurrences of...

The unique colors of the cashmere sweaters your firm makes result from heating undyed yarn in a kettle with a dye liquor. The pH (acidity) of the liquor is critical for regulating dye uptake and hence the final color. There are 6 kettles, all of which receive dye liquor from a common source. Past data show that pH varies according to a Normal distribution with μ = 4.86 and σ = 0.133. You use statistical process control to check the...
