Hint(s) Check My Work A population proportion is 0.30. A random sample of size 300 will be taken and the sample proportion p will be used to estimate the population proportion. Use the z-table. Round your answers to four decimal places. a. What is the probability that the sample proportion will be within ±0.03 of the population proportion? b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?
