6.9. On a toy assembly line, daily output for each worker averages 46.7 units with a standard deviation of 8.90 units. Assume the histogram of daily output looks approximately like the normal curve. a. On a given day, what percentage of workers have a daily output over 50 units? b. 25 workers are selected at random. What is the probability that their output for a given day will average 50 units or higher? c. 25 workers are selected at random. There is an 80% chance that their output will average below units.
