If a sample mean of x̄ = 15.82 ounces were found, what is the p-value? What action would you recommend?d. Use the critical value approach. What is the rejection rule for the preceding hypothesis testing procedure? Repeat parts (b) and (c). Do you reach the same conclusion?65.

Overfilling or underfilling presents a serious problem and when detected requires the operator to shut down the production line to readjust the...**Sample Size for a One-Tailed Hypothesis Test About a Population Mean**In a two-tailed test, replace $ z_\alpha $ with $ z_{\alpha/2} $.\[ n = \left( \frac{z_{\alpha/2} + z_\beta}{\mu_0 - \mu_a} \right)^2 \sigma^2\]\[ z = \frac{\bar{p} - p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}\]The text provides a brief exercise regarding production line concerns and offers formulas for calculating sample size and evaluating proportions in hypothesis testing.
