Useful Life The useful lifetime of a product is modeled by the probability density function
To calculate: The mean and median of the useful life time of a product modelled by the probability density
Given information:
The useful lifetime of a product modelled by the probability density function
Formula used:
If ‘f’ is the probability density function of a continuous random variable x over the interval
And, the median ‘x’ is the number m such that;
The formula for integration by parts is;
Calculation:
Consider given probability density function
Consider the primary equation
Solve by integration by parts
