Roll two fair dice, one red and one blue, and consider the events:
A: “The red die lands on 4”,
B: “The sum on the dice is 9” and
C: “The blue die lands on an odd number”.
Determine which pairs of events are independent.
The lifespan (in ‘000 hours) of four LED bulbs of 07 watts are as follows: 40,46,48, 50
(i) Write all samples of size 2without replacement from the above observations.Compute the sampling distribution and find mean and standard error of the distribution.
(ii) Write all samples of size 3 without replacement from the above observations. Compute the sampling distribution and find mean and standard error of the distribution.
(iii) Compare means and standard errors and draw the conclusion.
If X1, X2, X3, X4 and X5 is a random sample of size 5 taken from anExponential distribution, then estimator T1 is more efficient than T2.
What is the average length of the queen that forms from time to time?
State whether the following statements are True or False and also give the reason in support of your answer.
(a) If odds in favour of an event A are 3:5 then odds against of the event A will be 5:3.
(d) If X denotes the waiting time in minutes until the 3rd customer arrives in a mobile showroom, then X follows exponential distribution.
(e) The probability that a shooter hits a target in Olympic is 1/3. If she fires 6 times, then to calculate the probability of hitting the target at least 3 times we can use geometric distribution.
(a) Twenty pieces of different length of cloth contained 2, 4, 1, 3, 5, 4, 2, 7, 3, 5, 2, 2, 4, 5, 6, 4, 2, 1, 2, 4 defectsrespectively. To check the process is under control with respect to the number of defects, we should use p-chart.
(b) If density function of the time to failure of an appliance is
then reliability of the appliance for two years will be 0.444.
(c) If the probabilities are associated with the occurrence of different states of nature, then the situation is known as decision making under uncertainty.
(d) If there are 1% defectives notes of Rs.500 in a lot of 10000 notes of Rs 500, then the lot quality will be 99%.
(e) A system has four components connected in parallel configuration with reliability 0.2, 0.5, 0.4, 0.6. To improve the reliability of the system, we have to replace the weakest component to the more reliable component.
A leather bag manufacturing company supplies bags in lots of size 200 to a buyer. A sample of 2 begs is drawn and the corresponding lot is accepted if and only if both begs are nondefective. The company and the buyer decide that AQL = 0.04 and LTDD = 0.10. If there are 15 defective bags in each lot, compute the
(i) Probability of accepting the lot,
(ii) Producer’s risk and consumer’s risk,
(iii) AOQ, if the rejected lots are screened and all defective bags are replaced by nondefectives, and
(iv) Average total inspection.
