An industrial chemist is checking for the desired concentration of a certain chemical component in a batch of polymer blend. The target concentration is set at 8.2%. To verify
whether the actual average concentration matches the target for the current production line using a significance level of a = 0.05, 15 independently obtained samples are taken
for analysis. Assume that the concentration of the chemical component in a sample is normally distributed with o = 0.5% and that the sample mean is z = 8.0.
1. Based on the information provided, perform a hypothesis test to determine if there is statistical evidence that the true average concentration of the chemical component is
different from 8.2%. State the null and alternative hypotheses and calculate the P-value. Based on the P-value and the significance level, explain your conclusion. (10
points)
2. Assuming that the actual average concentration is µ = 8.1%, calculate the probability of committing a Type II error, denoted as ẞ(8.1). (10 points)
