Need someone to compare my solution with
a) 1 - P( x < 5 )
b) Confused on this part, maybe because of the wording. Should it be 1 - P(x <= 6) ***we get 6 since battery was bought year prior*
a)
here parameter β =10
| P(X<x)=(1/β)e-x/β= |
therefore P(battery last at least 5 years):
| probability = | P(X>5)= | 1-P(X<5)= | 1-(1-exp(-5/10))= | 0.6065 | ||
b)
as laptop battery is 1 year old, therefore for total life time to be more than 5 years, it has to stand at least 4 more years:
| probability = | P(X>4)= | 1-P(X<4)= | 1-(1-exp(-4/10))= | 0.6703 | ||
6) The lifetime battery life of a laptop can be modeled as a Weibull variable with parameter λ = 1 per 10 years and parameter a-1.35 a) What is the probability that a laptop will last between 5 and 10 years? b) A merchant sold 40 laptops on a day with a guarantee that any laptop lasting less than 5 years will be replaced by another laptop with a 28% discount. What is the probability that the merchant has to...

Problem 1 A subway train on the #5 line arrives every eight minutes. We are interested in the length of time a commuter must wait for a train to arrive. The time follows a uniform distribution In each appropriate box you are to enter either a rational number in "p/" format or a decimal value accurate to the nearest 0.01 a. The waiting time is modeled by a random variable X with X (pick on distribution b. The density function...
