The UPC code, made up of numbers and dashes, on a video tape is 9-78094-11006-$x$. The digit $x$ is in the $12^{\mathrm{th}}$ position. Let $n$ be the value obtained by adding the digits in the odd positions, tripling that sum, and then adding the digits in the even positions. A valid UPC code is such that $n$ is divisible by 10. For what value of $x$ will this UPC code be valid

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
