Justin records the speeds of vehicles moving past their house. The speed limit is 50 km/h. The mean ar standard deviation of 128 readings was 2-38.1 km/h and s=5.2 km/h. Assuming the data is normally distributed, what is the percent chance (approximately) that a person is travelling faster than 43.3 km/h? Use this Standard Normal Distribution curve to help answer the question: 19.1% 19.1%
