(Round your answer to two decimal places.) $ (b) Find the median price for the 14 different brands of tuna. $ (c) Based on your findings in parts (a) and (b), do you think that the distribution of prices is skewed? Explain. More information is needed to determine skewness. O Since the mean is larger than the median, the distribution is skewed to the right. O Since the median is larger than the mean, the distribution is skewed to the left. O Since the mean and median are equal, the distribution is not skewed.
