About 5% of employed adults in the United States held multiple jobs. A random sample of 75 employed adults is chosen. Use the TI84 Plus calculator as needed. (a) Is it appropriate to use the normal approximation to nd the probability that less than 6.5% of the individuals in the sample hold multiple jobs? If so, find the probability. If not, explain why not. (b) A new sample of 350 employed adults is chosen. Find the probability that less than 6.5% of the individuals in this sample hold multiple jobs. Round the answer to at least four decimal places. (1:) Find the probability that more than 6% of the individuals in the sample of 350 hold multiple jobs. Round the answer to at least four decimal plaoes. (d) Find the probability that the proportion of individuals in the sample of 350 who hold multiple jobs is between 0.05 and 0.10. Round the answer to at least four decimal places. (e) Would it be unusual if less than 4% of the individuals in the sample of 350 held multiple jobs
