Lab $3\mathrm{.}3$ Excel: Analysis Questions

In previous Chapter $3$ labs, you determined that the average sales transaction was different between online and in$-$person sales, but in this lab you actually assessed if those differences were significantly different using a hypothesis test. Why is statistically testing the differences important when it comes to making business decisions based on these results?

Assume that alpha is adjusted from $5\%$ to $10\%.$ With a $10\%$ alpha, is a Type II error more or less likely? What impact does that have on potential decision$-$making regarding this t$-$test?
