Question

Researchers often enter a lot of data into statistical software programs. The probability of making zero to two errors per 1,000 keystrokes is 0.56, and the probability of making three to five errors per 1,000 keystrokes is 0.24. Find the probabilities (per 1,000 keystrokes) associated with each of the following.

(a) at most two errors

(b) at least three errors

(c) at most five errors

(d) more than five errors

Answer #1

Researchers often enter a lot of data into statistical software
programs. The probability of making zero to two errors per 1,000
keystrokes is 0.53, and the probability of making three to five
errors per 1,000 keystrokes is 0.23. Find the probabilities (per
1,000 keystrokes) associated with each of the following.
(a) at most two errors
(b) at least three errors
(c) at most five errors
(d) more than five errors

Researchers often enter a lot of data into statistical software
programs. The probability of making zero to two errors per 1,000
keystrokes is 0.48, and thr probability of making three to five
errors per 1,000 keystrokes is 0.28. Find the probabilities (per
keystokes) associated with each of the following.
(a)
at most two errors (b) at least three errors (c) at most five
errors (d) more than five errors

People visiting video rental stores often rent more than one DVD
at a time. The probability distribution for DVD rentals per
customer at Video To Go is given in the table below. There is a
five-video limit per customer at this store, so nobody ever rents
more than five DVDs.

Oracle and PeopleSoft
Oracle Corporation makes extremely complicated and large customized
software programs that can support thousands of simultaneous users
and that are capable of administering the personnel records and
financial records of very large businesses (called enterprise
software). PeopleSoft and SAP were the only two other major
competitors making such massive enterprise software. Oracle held 18
percent of the market in customized software capable of handling
the personnel records of very large businesses, SAP held 29...

An article in Information Security Technical Report [“Malicious
Software—Past, Present and Future” (2004, Vol. 9, pp. 6–18)]
provided the following data on the top ten malicious software
instances for 2002. The clear leader in the number of registered
incidences for the year 2002 was the Internet worm “Klez,” and it
is still one of the most widespread threats. This virus was first
detected on 26 October 2001, and it has held the top spot among
malicious software for the longest...

4. Statistical measures of standalone risk
Remember, the expected value of a probability distribution is a
statistical measure of the average (mean) value expected to occur
during all possible circumstances. To compute an asset’s expected
return under a range of possible circumstances (or states of
nature), multiply the anticipated return expected to result during
each state of nature by its probability of occurrence.

Wayne Schuller managed a warehouse in Minnetonka,
Minnesota. His major concern was the number of workers to assign to
his single unloading dock. After he began contracting with motor
carriers for deliveries, he found that they were assessing him
stiff penalties if their trucks had to wait to be unloaded. Wayne
started adding larger crews at the unloading dock, but often they
seemed idle because there were no trucks to unload. Wayne recalled
from college that queueing theory might be...
