Question

The manufacturer wishes to set up a control chart at the final inspection station for a gas water heater. Defects in workmanship and visual quality features are checked in this inspection. For the past 22 working days, 176 wate rheaters were inspected and a total of 924 nonconformities were reported. a) What type of control chart would you reccommend here

Answer 1

Answer:

I will recommend a c chart

Explanation:

From the question, we have:

$n= 22\ working\ days$

$Inspection = 176$

$Noncomformities = 924$

First, it should be noted that a chart is used for a count datatype (in other words, numerical values) and they are usually discrete (i.e. whole numbers).

Notice that all the given data are whole digits.

Also, the c chart is to be used when the number of noncomformities are known because through the c chart shows the process of the noncomformities over specific time.
