3. [42.5 points] A world-renowned tech company is evaluating two programming languages. Ten data scientists, proficient in both programming languages, are asked to code 10 procedures in both languages, and the time in seconds) is recorded. Suppose you want to test whether the tech company should be indifferent to the choice of programming language. The following table shows the results for both data scientists.

A consumer products testing group is evaluating two competing brands of tires, Brand 1 and Brand 2. Tread wear can vary considerably depending on the type of car, and the group is trying to eliminate this effect by installing the two brands on the same random sample of 12 cars. In particular, each car has one tire of each brand on its front wheels, with half of the cars chosen at random to have Brand 1 on the left front...
