Based on the graph of this normal distribution. Image Caption: The chart shows a normal distribution with data points at the middle and spaced equally three positions in each direction from the middle, corresponding to standard deviations. The data points, from left, are 85, 95, 105, 115, 125, 135, 145. The mean, median and mode are, respectively: 115, 125 and 105 115, 112 and 118 115, 115 and 115 cannot be determined without calculations
