Suppose that prices of a gallon of milk at various stores in one town have a mean of $3.74 with a standard deviation of $0.09. using chebyshev's theorem, what is the minimum percentage of stores that sell a gallon of milk for between $3.56 and $3.92? round your answer to one decimal place.

Note that $3.56 is 2 standard deviations below the mean, and $3.92 is 2 standard deviations above the mean.

Chebyshev's theorem says that

In this case we take , and we're given and , so

making the minimum percentage 75%.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
