A company that packages peanuts states that at a maximum 6% of the peanut shells contain no nuts. At random, 300 peanuts were selected and 21 of them were empty. 1. With a significance level of 1%, can the statement made by the company be accepted? State the null and alternative hypotheses: Calculate the critical value Decide: 2. With the same sample percentage of empty nuts and 1 - a = 0.95, what sample size would be needed to estimate the proportion of nuts with an error of less than 1%?
