Atire manufacturer is considering a newly designed tread pattern for its all-weather tires. tests have indicated that these tires will provide better gas mileage and longer tread life. the last remaining test is for braking effectiveness. the company hopes the tire will allow a car traveling at 60 mph to come to a complete stop within an average of 125 feet after the brakes are applied. they will adopt the new tread pattern unless there is strong evidence that the tires do not meet this objective. the distances (in feet) for 10 stops on a test track were 129, 128, 130, 132, 135, 123, 102, 125, 128, and 130. should the company adopt the new tread pattern? test an appropriate hypothesis and state your conclusion. explain how you dealt with the outlier and why you made the recommendation you did.

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
