Stopping Distance (ft) 18.0 18.0 18.1 18.5 18.5 19.1 19.2 20.0 20.1 20.5 22.0 22.1 22.3 22.5 23.0 23.0 24.0 24.0 24.0 24.1 25.2 25.9 26.0 26.5 27.2
Problem 1.2 Highway traffic and safety engineers choose road speed limits considering several factors, such as characteristics of the road, braking deceleration distance, and many more. Eleven different automobiles were tested for stopping distances at a speed of 10 miles per hour. The data, in feet, are shown in file pr1_2. Find the mode, mean, median and standard deviation. Analyze the distribution of the sample and interpret the dispersion measure. MEASURES OF Mean: 22 CENTRAL TENDENCY Median: Shape of Distribution: _Positively Skewed Negatively Skewed _Symmetrical Mode: L4.O Interpretation of Standard Deviation Empirical Rule orChebychev: Range: .2 Number of Standard Deviations used: Computations: MEASURES OF Variance: 3.8 VARIABILITY Standard Deviation: 4.853 Interpretation of Standard Deviation: -35
