A: Show the sampling distribution of ( p¯ ), the proportion of groceries thrown out by your sample respondents. B: What is the probability that the sample proportion will be within ±.04 of the population proportion? C: What is the probability that your survey will provide a sample proportion within ±.025 of the population proportion?
