About 6% of employed adults in the United States held multiple jobs. A random sample of 69 employed adults is chosen. Use the TI-84 Plus calculator as needed. Part 1 of 5 (a) Is it appropriate to use the normal approximation to find the probability that less than 6.6% of the individuals in the sample hold multiple jobs? If so, find the probability. If not, explain why not. It is not v appropriate to use the normal curve, since np = 4.14 10. Part 2 of 5 (b) A new sample of 339 employed adults is chosen. Find the probability that less than 6.6% of the individuals in this sample hold multiple jobs. Round the answer to at least four decimal places. The probability that less than 6.6% of the individuals in this sample hold multiple jobs is 0.6791
