Please Answer the following Questions and explain how you derived at each of the following answers.
\n" ); document.write( "· What symbol do we use for representing the mean of a population and what symbol do we use to represent the mean of a sample that you have taken?
\n" ); document.write( "---
\n" ); document.write( "population mean = mu = u
\n" ); document.write( "sample mean = x-bar or maybe y-bar

\n" ); document.write( "1) the area under the curve is 1
\n" ); document.write( "2) The range of the z or t values is approximately 6sigma.

\n" ); document.write( "---
\n" ); document.write( "7000 to 9000 covers the interval within 1 standard deviation of the mean.
\n" ); document.write( "Chebyshev's Rule only states that there will be at least 1-[1/1^2]% = 0%
