Because of the high physical demands of the job, the company's policy is a 25% allowance for workers. (Round all intermediate calculations to two decimal places before proceeding with further calculations.) Bag breaks open; included as delay in the allowance factor Conveyor jams; included as delay in the allowance factor The standard time for this process - 86.14 seconds (round your response to two decimal places) The number of observations that are required for a 99% confidence level within 5% accuracy = observations (round your response up to the next whole number).
