A sample of the labor cost per hour to assemble a certain produce has a mean of $2.60 and a standard deviation of $0.15. Using Chebyshev's theorem, find the range in which at least 88.89% of the data will lie.

• $2.45 - $2.75

• $2.15 - $3.05

• -$10.73 - $15.93

The mean of a distribution is 20 with a standard deviation of 2. Use Chebyshev's theorem.

At least what percent of the values will fall between 10 and 30? What is the K VALUE ONLY?
