(a) What is the meaning of the P-value? (b) What is the meaning of α-level? (c) We tested the null hypothesis that the weight of a McDonald's quarter pounder is 0.25 pounds (H0 : µ = 0.25) against the alternative that the weight is below 0.25 pounds (Ha : µ < 0.25). After collecting a sample our observed z statistic was z = -2.02. Find the largest level at which the hypothesis testing procedure does not reject H0.
