A consumer protection testing agency wants to study the life expectancy of a particular job lot of a new radial tire. Ten tires were randomly selected from the job lot. Achieved mileages before the minimum tread depth was reached (and the tires were declared worn out) were: 32,800; 41,700; 35,200; 39,000; 36,200; 35,600; 35,700; 45,200; 42,800; and 35,700.A) Construct a frequency distribution and cumulative frequency distribution for the data.
B) Using the frequency distribution in part A, draw a histogram of the recorded mileages for the 10 new radial tires.
C) Is a run chart an appropriate display for the data? Explain why or why not, and if so, construct a run chart.
D) Calculate the mean life expectancy for this sample of 10 tires.
E) Calculate the median life expectancy for this sample of 10 tires.
F) Calculate the modal life expectancy for this sample of 10 tires.
G) Calculate the standard deviation of the life expectancy of the sample of the sample of 10 tires.
H) Calculate the rage for the data.
