Pay your taxes: According to the Internal Revenue Service, the proportion of federal tax returns for which no tax was paid was p = 0.326. As part of a tax audit, tax officials draw a simple random sample of n = 130 tax returns. Use the TI-84 Plus calculator as needed. Part 1 of 4 (a) What is the probability that the sample proportion of tax returns for which no tax was paid is less than 0.28? Round the answer to at least four decimal places. The probability that the sample proportion of tax returns for which no tax was paid is less than 0.28 is Part 2 of 4 X S (b) What is the probability that the sample proportion of tax returns for which no tax was paid is between 0.35 and 0.42? Round the answer to at least four decimal places. The probability that the sample proportion of tax returns for which no tax was paid is between 0.35 and 0.42 is X
