1. For each day of last year, the number of vehicles passing through a certain intersection was recorded by a city engineer. One objective of this study was to determine the percentage of days that more than 425 vehicles used the intersection. If the mean data was 375 vehicles per day and the standard deviation was 25 vehicles: (d) Suppose the relative frequency distribution for the data is bell-shaped, then what percentage of days more vehicles used the intersection ? 16% 5% 32% 2.5% than 425
