1) Consider writing onto a computer disk and then
sending it through a certifier that counts the number of missing
pulses. Suppose this number X has a Poisson distribution
with parameter ? = 0.14.
(a) What is the probability that a disk has exactly one missing
pulse? (Round to four decimal places)
(b) What is the probability that a disk has at least two missing
pulses? (Round to four decimal places)
(c) If two disks are independently selected, what is the
probability that neither contains a missing pulse?(Round to four
decimal places)
The National Center for Health Statistics estimates that
16.9 percent of U.S. children and adolescents aged 2 to 19 were
obese in 2009-2010. Assume that this obesity rate holds true today.
If you were to randomly select 16 U.S. children or adolescents,
find each of the following:
Note1: carry at least 6 digit precision for any intermediate
calculations then round your answer to 4 decimal places
Note2: Any value that is less than 0.0001, (1 x 10-4) ,
can be rounded to 0
The probability that at least 2 people in the sample
will be obese is: _______________
