Let the mean of X be 10 and the standard deviation of X be 5. Find the greatest
lower bound of P(| X −10 |< 10) .
We know that the standard deviation of daily output on a production line for steel pipe
is σ = 10 tons. We want to estimate the mean daily output of the production line, μ ,
to within ±2.5 tons with 95% confidence. What sample size is required?
State the relationship between the standard normal distribution and the chi-square
distribution with r degrees of freedom.
State the relationship between the gamma distribution with parameters α and β and
the chi-square distribution with r degrees of freedom.
