1. The time (in hours) until failure of a transistor is a random variable X which is exponentially distributed with mean = 50. It is observed that after 40 hours the transistor is still working. Find the conditional probability that X > 65.
2. Wires manufactured for the use in a computer system are specified to have resistances between 0.12 and 0.14 ohms. The actual measured resistances of the wires produced by company A have a normal distribution with a mean of 0.13 ohm and a standard deviation of 0.005 ohm. Find the probability that a randomly selected wire from company A's production will meet the specifications.
A random sample of size 25 is taken from a normal population having a mean of 80 and a standard deviation of 5. A second random sample of size 36 is taken from a different normal population having a mean of 75 and a standard deviation of 3.
A data source generates hexadecimal characters. Let X be the integer value corresponding to a hex character. Suppose that the four binary digits in the character are independent and each is equally likely to be 0 or 1.
The data below show the average daily high temperature for Chicago, Illinois, for twelve recent spring and summer months. Create a stem-and -leaf diagram for the data.
The accompanying table summarizes randomly selected sample data for San Francisco Defendants in burglary cases.
The following is the number of minutes to commute from home to work for a group of automobile executives.
Illustrate out the term control chart? Critically discuss the grand mean, the UCL and the LCL of a control chart for the mean?
In testing a new drug, researchers found that 20% of all patients using it will have a mild side effect. A random sample of 15 patients using the drug is selected. Find the probability that:
An element E has a constant failure rate λ and a reliability at time t of R(t)=p, if p=0.5 and 0.9, what is the effect on Rs(t), basic reliability, serial Mean Time Between Failure, hs(t), MTBFs if additional elements are added to the baseline sys..
Which of the variables below do you think will be roughly normally distributed? Please select all that apply.
Select an activity you do on a regular basis (e.g., cooking a meal, cleaning the house, doing homework, etc.) and discuss how you could apply statistical quality control to improve the quality of the output of the activity you choose.
Using the .02 level of significance, conduct a five-step hypothesis testing procedure to determine if the new processes significantly reduced the wait time.
If computing a causal linear regression model of y = a + bX and the resultant r2 is very near zero, then one would be able to conclude that:
