2.

If a process is deemed to be functioning properly when it is in fact out of control, which of the following is true?

	a.	A Type I error has occurred which is the producer's risk.
	b.	A Type II error has occurred which is the producer's risk.
	c.	A Type I error has occurred which is the consumer's risk.
	d.	A Type II error has occurred which is the consumer's risk.
	e.	None of the above.

3.

A control chart is used to plot average values of a performance measure over time to determine if the performance mean and variance of the process change.

True

False

Expert Solution

Answer 2 : D. A Type II error has occurred which is the consumer's risk

Note : In this type of error system seems to be functioning properly while in fact it is out of control, such errors are difficult to predict and its called consumer's risk

Answer 3 : True

Note : Control charts in statistics are used to plot average values of performance measures over time to check if the mean and variance of the process change as they are usually used to determine process change over time.

When a new machine is functioning properly, only 3% of the items produced are defective. Assume that we will randomly select ten parts produced on the machine and that we are interested in the number of defective parts found. Compute the probability associated with: a. [4 points] No defective parts b. [6 points] At least 1 defective parts. 2. [12 points] Over 500 million tweets are sent per day (Digital Marketing Ramblings website, December 15, 2014).

a) Competition is a necessary component to properly functioning markets. What happens when markets lack competition? Is this a reason for government involvement? For example, should the government have sought to break up the Microsoft Corporation? b) How do taxes influence people's behavior? In your answer, be sure to discuss such concepts as the tax rate, tax base, and tax revenue.

QUESTION 2: When a manufacturing process is operating properly, maximum length of a certain part must be 25cm. The lengths which are more than 25cm are scrap. If the proportion of scrap is more than 0.171255, then a modification of the process is needed to reduce this amount. On one production run, a random sample of 50 consecutive parts are selected and the following lengths are observed. 19.52 23.15 23.17 18.33 25.68 18.51 20.63 25.68 21.21 26.58 19.85 19.63 20.58...

When things are operating properly, a certain Internet bank can process a maximum of 28 electronic transfers every minute during the busiest periods of the day. If it receives more transfer requests than this, then the bank's computer system will become so overburdened that it will slow to the point that no electronic transfers can be handled. If during the busiest periods of the day requests for electronic transfers arrive at the rate of 180 per 10-minute period on average,...

In a properly validated biotechnology process (i.e., it was proven that the process occurs in the same way each time it is run) three samples of the product are taken during a manufacturing stage to verify the percentage of the active ingredient. The researcher suspects that the first sample influences the result of the second and in turn the second influences the result of the third. For this reason, the researcher decided to compare lots to verify if the samples...

When the manufacturing process is working properly, NeverReady batteries have lifetimes that follow a slightly right-skewed distribution with µ = 7 hours. A quality control supervisor selects a simple random sample of n batteries every hour and measures the lifetime of each. If she is convinced that the mean lifetime of all batteries produced that hour is less than 7 hours at the 5% significance level, then all those batteries are discarded. a. State appropriate hypotheses for the quality control...
