Normal probability plots for three data sets are shown on the next page. Which plot indicates that the data are approximately normally distributed?

Short Answer

Expert verified

The plot in part-(c) indicates that data is normally distributed.

Step by step solution

01

Given Information

02

Explanation

In the first plot (i.e,part-(a))if we draw a straight line then maximum data points fall below the straight line, so the data is not normally distributed.

In the second plot (i.e,part-(b))if we draw a straight line then maximum data points fall above the straight line, so the data is not normally distributed.

In the third plot (i.e, part-(c) if we draw a straight line then maximum data points fall on the straight line, so the data is normally distributed.

Space shuttle disaster. On January 28, 1986, the space shuttle Challenger exploded, killing all seven astronauts aboard. An investigation concluded that the explosion was caused by the failure of the O ring seal in the joint between the two lower segments of the right solid rocket booster. In a report made 1 year prior to the catastrophe, the National Aeronautics and Space Administration (NASA) claimed that the probability of such a failure was about 1/ 60,000, or about once in every 60,000 flights. But a risk-assessment study conducted for the Air Force at about the same time assessed the probability to be 1/35, or about once in every 35 missions. (Note: The shuttle had flown 24 successful missions prior to the disaster.) Given the events of January 28, 1986, which risk assessment鈥擭ASA's or the Air Force's鈥攁ppears more appropriate?

How many questionnaires to mail? The probability that a consumer responds to a marketing department鈥檚 mailed questionnaire is 0.4. How many questionnaires should be mailed if you want to be reasonably certain that at least 100 will be returned?

When to replace a maintenance system. An article in the Journal of Quality of Maintenance Engineering (Vol. 19,2013) studied the problem of finding the optimal replacement policy for a maintenance system. Consider a system that is tested every 12 hours. The test will determine whether there are any flaws in the system. Assume that the probability of no flaw being detected is .85. If a flaw (failure) is detected, the system is repaired. Following the fifth failed test, the system is completely replaced. Now, let x represent the number of tests until the system needs to be replaced.

a. Give the probability distribution for x as a formula.

b. Find the probability that the system needs to be replaced after 8 total tests.

Elevator passenger arrivals. A study of the arrival process of people using elevators at a multilevel office building was conducted and the results reported in Building Services Engineering Research and Technology (October 2012). Suppose that at one particular time of day, elevator passengers arrive in batches of size 1 or 2 (i.e., either 1 or 2 people arrive at the same time to use the elevator). The researchers assumed that the number of batches, n, arriving over a specific time period follows a Poisson process with mean 位=1.1. Now let xn represent the number of passengers (either 1 or 2) in batch n and assume the batch size has probabilities p=P(xn=1)=0.4andq=P(xn=2)=0.6. Then, the total number of passengers arriving over a specific time period is y=x1+x2+...+xn. The researchers showed that if x1,x2,...xnare independent and identically distributed random variables and also independent of n, then y follows a compound Poisson distribution.

a. Find P(y=0), i.e., the probability of no arrivals during the time period. [Hint: y = 0 only when n = 0.]

b. Find P(y=1), i.e., the probability of only 1 arrival during the time period. [Hint: y = 1 only when n = 1 and x1=1.]

Detecting a computer virus attack. Chance (Winter 2004) presented basic methods for detecting virus attacks (e.g.,Trojan programs or worms) on a network computer that are sent from a remote host. These viruses reach the network through requests for communication (e.g., e-mail, Web chat, or remote log-in) that are identified as 鈥減ackets.鈥� For example, the 鈥淪YN flood鈥� virus ties up the network computer by 鈥渇looding鈥� the network with multiple packets. Cyber security experts can detect this type of virus attack if at least one packet is observed by a network sensor. Assume that the probability of observing a single packet sent from a new virus is only .001. If the virus actually sends 150 packets to a network computer, what is the probability that the virus is detected by the sensor?
