Normal or random variations that are considered part of operating the system at its current capability are <u> c. common cause variations.</u>

Explanation:

Common cause variation is fluctuation caused by unknown factors resulting in a steady but random distribution of output around the average of the data.

Common-cause variation is the natural or expected variation in a process.

Common-cause variation is characterised by:

Phenomena constantly active within the system
Variation predictable probabilistically
Irregular variation within a historical experience base

It is a measure of the process potential, or how well the process can perform when special cause variation removed.

Common cause variation arises from external sources that are not inherent in the process and is where statistical quality control methods are most useful.

Statistical process control charts are used when trying to monitor and control 5- and 6-sigma quality levels.

A program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day is given below:

<h3>The Program</h3>

input_month = input()

input_day = int(input())

months= ('January', 'February','March', 'April' , 'May' , 'June' , 'July' , 'August' , 'September' , "October" , "November" , "December")

if not(input_month in months):

print("Invalid")

elif input_month == 'March':

if not(1<=input_day<=31):

print ("Invalid")

elif input_day<=19:

print("Winter")

else:

print ("Spring")

elif input_month == 'April' :

if not(1<=input_day<=30):

print("Invalid")

else:

print("Spring")

elif input_month == 'May':

if not(1<=input_day<=31):

print("Invalid")

else:

elif input_month == 'June':

if not(1<=input_day<=30):

print("Invalid")

elif input_day<=20:

print ("Spring")

else:
