1.11 A quick survey gives the price—an estimated average for a 170-gram can—for 14 different brands of water-packed light tuna, based on prices paid nationally in supermarkets. 1.01 1.92 1.22 0.84 0.65 0.52 1.41 1.14 0.65 0.66 0.71 0.60 0.61 0.67 Find the average price and average median price for the 14 different brands of tuna. (Round your answers to two decimal places and show answers.) Based on your findings, do you think that the distribution of prices is skewed? Explain. a) Since the median is higher than the mean, the distribution is slightly skewed to the left. b) More information is needed to determine skewness. c) Since the mean is higher than the median, the distribution is slightly skewed to the right. d) Since the mean and median are equal, the distribution is not skewed.
