minutes, with a maximum variance of minutes.The sample average is minutes, with a -minute standard deviation.
minutes, with a -minute standard deviation.So, based on the information provided, we can deduce that the traveler is questioning the claim regarding the variation rather than the average. The variance is the subject of all of the preceding information. By taking the square of the sample standard deviation, we can get the sample variance.
Therefore, the assertion is that the difference is less than minutes.
