Question
please help to solve
The New York Times reported that the mean time to download the homepage for the Internal Revenue Service is 0.75 seconds. What is the probability that it takes you than 1 second to download the page? (Use an exponential distribution to determine this probability.) Use the following information to help you: e^-0.1 = 9048 e^-0.4 = 6703 e^-0.8 = 4493 e^-1.6 = 2019 e^-3 = 0498 e^-0.167 = 8465 e^-0.417 = 6592 e^-0.833 = 4346 e^-1.667 = 1889 e^-3.333 = 0357 e^-0.2 = 8187 e^-0.45 = 6376 e^-0.9 = 4066 e^-1.8 = 1653 e^-3.75 = 0235 e^-0.25 = 7788 e^-0.5 = 6065 e^-1 = 3679 e^-2 = 1353 e^-4 = 0183 e^-0.267 = 7659 e^-0.6 = 5488 e^-1.2 = 3012 e^-2.25 = 1054 e^-5 = 0067 e^-0.3 = 7408 e^-0.625 = 5353 e^-1.25 = 2865 e^2.4 = 0907 e^-6 = 0024 e^-0.333 = 7165 e^-0.667 = 5134 e^-1.333 = 2636 e^-2.5 = 0821 e^-8 = 0003 e^-0.375 = 6873 e^-0.75 = 4724 e^-1.5 = 2231 e^-2.667 = 0695 e^-10 = 0000 3515 2636 6277 4723 3679 7364
Explanation / Answer
here above part has been cut down; therefore if it is more then 1 second probability =e-1/0.75 =0.2636 option b
if it is less then 1 second ; probability =1-0.2636=0.7364 option f
