How does it suggest that the sample mean and median will compare? The display is positively skewed, so the median will be greater than the mean. The display is reasonably symmetric, so the mean and median will be close. The display is negatively skewed, so the median will be greater than the mean. The display is positively skewed, so the mean will be greater than the median. The display is negatively skewed, so the mean will be greater than the median. (b) Calculate the values of the sample mean x and median x tilde. [Hint: Σxi = 9643.] (Round your answers to two decimal places.) x = sec x tilde = sec (c) By how much could the largest time, currently 425, be increased without affecting the value of the sample median? (Enter [infinity] if there is no limit to the amount.) By how much could this value be decreased without affecting the value of the sample median? (Enter [infinity] if there is no limit to the amount.)
