Assume that a hypothesis test will be conducted using significance level α = .01 and alternative hypothesis Ha: μ : ≠ 19.3.

Furthermore, we will use the following sample data: n = 12, x-bar = 18.8, and s = 2.1.

Expert Solution

The concept of hypothesis testing of population mean and the form of the null and alternate hypothesis in such test procedure is needed to be known as a prerequisite for understanding the solution to the problem done. Our answer to the problem is that we have insufficient evidence to reject the null hypothesis "H0: mu=19.3", mu= population mean (given in terms of symbol). The solution is attached below:

In a hypothesis test, the significance level α (alpha) represents the threshold for how unlikely sample data has to be, assuming the null hypothesis, in order for us to reject the null hypothesis. Often alpha is taken to be 0.05, or 1/20, which means that even if the null hypothesis is true, there is a 1/20 chance that we will reject it because our sample data happens to have a P-value less than 0.05. We want to study the heights...
