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.

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
