The lifetime (in miles) of bicycle tires produced by a manufacturer is a normally distributed random variable with a mean of 3000 miles and a standard deviation of 150 miles. Marketing research by the manufacturer has indicated that if a tire lasts 3270 or more miles, the customer will definitely purchase another of these tires. What percentage of all tires produced by this company will have a lifetime of 3270 or more miles?

8 2/3 is the answer

step-by-step explanation: just use a calculator

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05
