Cellophane that is going to be formed lnto bags for lterns such as dried beans or bird seed is passed over a light sensor to test lf the alignment is correct before it passes through the healing umts that seal the edges, Small adjustments can be made by the machine automatically, But lf the alignment is loo bad, the process is stopped and an operator has to manually adjust it These mlsalig nment stops occur randomly and independently, On one line, the average number of stops is 63 per 8-hour shitt Suppose the number of stops can be modeled by a Poisson disinbution Complete pans a and b below a) Whal l5 the mean number of stops per hour') The mean is stops per hour (Round to three decimal places as needed.) b) What is lhe standard devtation of stops per hour? The standard devlation is stops per hour (Round to three decimal places as needed )
