People end up tossing 12% of what they buy at the brocery store.Assume this is the true population proportion and that you plan to take a sample survey of 264 grocery shoppers .

1. compute the standard error of the sample proportion (use 2 decimal places)
2. what is the probability that your survey will provide a sample between 0.105 and 0.135?( answer using 4 decimal places)
3. what is the probability that the survey will provide a sample proportion less than 0.10? (Answer using 4 decimal places).

Thank you !
