Probability Distribution Function is a likelihood of an event to occur for discrete random variables. Graphically, it shows how likely variables will fall under the probability area.
Exponential distribution is a probabilitydistribution which finds probability of an event to occur between independent constant rate and continous rate.

63. X control charts are used to maintain control of the manufacture of the cases used to
house a generic brand of personal computer. Separate charts are maintained for length,
width, and height. The length chart has UCL = 20.5 inches, LCL = 19.5 inches, and a
target value of 20 inches. This chart is based on using subgroups of size 4 and three-
sigma limits. However, the customer's specifications require that the target length
should be 19.75 inches with a tolerance of ±0.75 inch. What percentage of the
cases shipped will fall outside the customer's specifications?

- Designing an x -Chart Using the Process Standard DeviationThe Sunny Dale Bank monitors the time required to serve customers at the drive-through window because it is an important quality factor in competing with other banks in the city. After analyzing the data gathered in an extensive study of the window operation, bank management determined that the mean time to process a customer at the peak demand period is 5 minutes, with a standard deviation of 1.5 minutes. Management wants to monitor the mean time to process a customer by periodically using a sample size of six customers. Assume that the process variability is in statistical control. Design an x-chart that has a type I error of 5 percent. That is, set the control limits so that there is a 2.5 percent chance a sample result will fall below the LCL and a 2.5 percent chance that a sample result will fall above the UCL. After several weeks of sampling, two successive samples came in at 3.70 and 3.68 minutes, respectively. Is the…arrow_forward1.
