Answer:
0.14% probability of observing more than 4 errors in the carpet
Explanation:
When we only have the mean, we use the Poisson distribution.
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
The number of weaving errors in a twenty-foot by ten-foot roll of carpet has a mean of 0.8.
This means that
What is the probability of observing more than 4 errors in the carpet
Either we observe 4 or less errors, or we observe more than 4. The sum of the probabilities of these outcomes is 1. So
We want P(X > 4). Then
In which
0.14% probability of observing more than 4 errors in the carpet
The program that can display an appropriate error message if an invalid rating is illustrated below.
<h3>How to illustrate the program?</h3>
The program for the error message will be:
CONSTANTS
RAISE_FACTOR = 2400.00
UNACCEPTABLE = 0.0
ACCEPTABLE = 0.4
MERITORIOUS = 0.6
# input of user rating
rating = float(input('Enter your rating: '))
# based on rating display the performance and salary raise
if rating == UNACCEPTABLE:
print('Your performance was UNACCEPTABLE. Raise in salary: $%.2f' %(RAISE_FACTOR*UNACCEPTABLE))
elif rating == ACCEPTABLE:
print('Your performance was ACCEPTABLE. Raise in salary: $%.2f' %(RAISE_FACTOR*ACCEPTABLE))
elif rating == MERITORIOUS:
print('Your performance was MERITORIOUS. Raise in salary: $%.2f' %(RAISE_FACTOR*MERITORIOUS))
else: # invalid rating
print('Invalid Rating. Valid ratings are 0.0, 0.4 and 0.6')
