Concept explainers
a
Interpretation:
Circumstances in which “The probability law describing the number of periods until the process goes out of control follows the geometric distribution” will fail.
Concept Introduction:
Geometric distribution consider a sequence of Bernoulli trials, with constant probability of success p in a single trial.
b
Interpretation:
Circumstances in which “The assumption that an out of control condition corresponds to a a shift of the mean equal to
Concept Introduction:
Standard deviation measures the spread of random variables or the given data from central tendency values or mean. It shows how far the deviation is from mean. A low value of standard deviation shows values are close to mean.
c
Interpretation:
Circumstance in which “ the assumption that the search cost is a fixed constant
Concept Introduction:
Search cost is a transaction cost. It shows the amount of costs required to find a better product. If the cost gets higher, it leads to increase in transaction cost, thereby becoming a loss to consumer.

- An urn contains two red and two green balls. The balls are chosen at random, one by one, from the urn. If a red ball is chosen, it is removed. Any green ball that is chosen is returned to the urn. The selection process continues until all of the red balls have been removed from the urn. a) ) Find a transition probability matrix P. Find the expected number of transitions until the process ends. b) Find the mean time spent in state 2 until the process ends. c) ) Does a stationary distribution exist for this Markov chain? If so, what is it? If not, explain why it doesn’t exist. please answer parts a, b, and c.arrow_forwardA cosmetics company fills its best selling jars of facial cream by an automatic dispensing machine. The machine is set to dispense a mean of 7.2 ounces per jar. Uncontrollable factors in the process can cause either underfill or overfill, both of which are undesireable. In such a case, the dispensing can be stopped and recalibrated. Regardless of the mean amount despensed, the standard deviation of the amount dispwnsed always has a value of 0.25 ounce. A quality control engineer routinely selects 36 jars from the assembly line to check the amounts filled. On one occasion, the sample mean is 7.8 ounces. Determine if there is sufficient evidence in the sample to indicate, at the 1% level of significance, that the machine should be recalibrated.arrow_forwardSuppose that you have a four-sided die that is equally weighted (i.e. equal chance of any of the four sides landing face up). The four values on the die are [12.5968, 2, -2 and -12.5968] . Say we roll the die 81 times, record the average, and repeat this process a total of 100 times. According to the Central Limit Theorem and the 68-95-99.7 rule, what is the probability of obtaining an average of -1 or less based on the facts above? Assume that n is adequately large.

The desired speed of a cassette tape is 1.900 inches per second. Any deviation from this value causes a change in pitch and tempo and thus poor sound quality. Suppose that adjusting the tape speed under warranty when a customer complains and returns a device costs a manufacturer $20. Based on past information, the company knows the average customer will return a device if the tape speed is off the target by at least 0.200 inches per second; in other words, when the speed is either 2.100 or 1.700.
