# Analysis of Data Using P-chart

Question

The manager of a U.S. private hospital is conducting a study at the maternity unit to analyze the number of complaints at the nurse station made by families giving birth. For this purpose, he collected data from 20 weeks to create 20 samples (corresponding to each week) of 100 births each. He also gathered information on whether a birth gave rise to a complaint or not. The table below summarizes the data collected:

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
