You are building a single family residence and are using 2x6 stud walls to build it. You don't have any existing testing data or standard deviation on 2x6 wood. However, you do have access to testing equipment and you test 30 2x6's that determine the mean compressive strength is 2000psi and standard deviation of the sample is 600psi. a) Use a 't-distribution', determine the 99% lower bound for the distribution of the sample data(i.e one trail) and explain your value.
