4. (20) Suppose that a pharmaceutical company has been contracted by Walgreen\'s to produce their generic brand of 200 mg ibuprofen tablets. Four different processes are being investigated. 150 tablets are collected for inspection from each of four processes and the dotplots of their potencies(in mg) given below: Write a paragraph describing each of processes. Your paragraph should contain information about the shape, center, and variability in the potencies for each of the processes. Write another paragraph comparing these distributions. Your paragraph should include answers to the following questions: Which process is the best and why? Which process is the most stable, i.e., has the least variability in potency? Which process is the least stable? Which two processes have very similar ranges, but actually have different levels of variability? Which one of them has less variability?

Solution

Process F is the best as it is symmetrical bell shaped and has less std deviation.

Most stable is process F.

Least stable is process E

Processes E and G have the same range but different variability
