Extracted text: Listed below are the arrival delay times (in minutes) of randomly selected airplane flights from one airport to another. Negative values correspond to flights that arrived early before the scheduled arrival time, and positive values represent lengths of delays. Find the range, variance, and standard deviation for the set of data. Some of the sample values are negative, but can the standard deviation ever be negative? -8 - 2 - 14 - 29 - 19 -8 - 5 minutes The range of the sample data is (Round to one decimal place as needed.) The variance of the sample data is minutes. (Round to one decimal place as needed.) minutes. The standard deviation of the sample data is (Round to one decimal place as needed.) Some of the sample values are negative, but can the standard deviation ever be negative? O No, because the squared value in the standard deviation formula cannot be negative. Yes, because the squared value in the standard deviation formula can be negative. No, because the squared value in the standard deviation formula can be negative. Yes, because the squared value in the standard deviation formula cannot be negative.
