The city of Nashville determined in 2009 that the population mean weight of municipal solid waste (MSW) generated per person per day was 6.40 lbs with a population standard deviation of 1.44 lbs. Assume a normal distribution. With the objective of promoting recycling of MSW and of reducing the costs of landfill disposal, the Nashville city council decides to propose a curbside recycling program that would assure that daily, per person MSW generation should not exceed the 10th percentile value of the distribution reported above. What is that value in pounds? Sketch the distribution and indicate the location of the value sought.
