Question

Battery packs in electric go-carts need to last a fairly long time. The run-times (time until recharging is needed) of the battery packs made by a particular company are Normally distributed with a mean of 2 hours and a standard deviation of 20 minutes. Battery packs that have a runtime in the highest 10% of the run-time distribution are highly sought after by go-cart drivers. How long does the battery pack have to last for it to fall in this highly sought-after class? (Enter the number of hours as a whole number and the number of minutes as a decimal rounded to 1 decimal place.)

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
