1) If a process is Normally distributed what is the relationship between a run chart
and a control chart of this process performance? Please discuss. 2) A project manager needs to choose a machine that molds 1-inch plastic water
pipe. The 1-inch pipe has a specification of 1-inch plus or minus 0.1 inch.
Determine which machine he should choose, by computing and interpreting the
process capability index for each machine.

organization?s software development process. He has the size of each project in
number of lines of code for the past 20 projects and the number of design errors
discovered in design reviews for each project. . 4 Describe what type of control chart you can use and how do you calculate the
control limits to check if the software design process in this organization is in
control.
4) A project manager at System Design Corporation has collected the following data
on the size of software programs and the length of programming time. The
company is bidding on a new system that is estimated to consist of 250000 lines
of code. Please use the data to find the functional relationship of the coding time
to the program size and estimate the number of days it would take to code the new
system.
