The average years of employment is 14
with 73% having worked for at least 10 years.
To find the mean, add up the years of service and divide by the number of employees. The total years worked is 417, so the formula yields:
average years worked = 417/30 = 13.9, rounded to approximately 14 years.
To determine the percentage of employees with ten or more years, count those with 10 or more years and divide by the total employee count, converting the result into a percentage:
(10 years or over)/(total number) = 22/30 = 0.73 repeating, which approximates to 73%.
Using a spreadsheet tool can make this calculation simpler, as it can quickly compute the average and help tally how many employees have worked for 10 years or more.
Answer:
P(functioning product) =.99*.99*.96*.96 =.0.903
Step-by-step explanation:
In order for the product to function, all four probabilities must succeed, hence:
P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4)
where:
P(Part-1) = 0.96
P(Part-2) = 0.96
P(Part-3) = 0.99
P(Part-4) = 0.99
Since each part is independent, we apply the formula P(A∩B) = P(A)*P(B)
P (Functioning Product) = P(Part-1)*P(Part-2)*P(Part-3)*P(Part-4)
P (Functioning Product) = 0.96*0.96*0.96*0.99*0.99
P(Functioning Product) = 0.903
