Let's assume your process yields products with a mean diameter of 12.50mm and σ = 0.010mm. If the specification calls for a range of 12.480mm - 12.530mm, what percentage of parts will have a diameter within these limits?

Expert Solution

So, 97.59% of parts will have a diameter with in these limis.

If you any doubts regarding calculation let me know. Thank you.

Let's assume that your process yields products with a mean diameter of 1.251mm with σ = 0.00083mm. The Process Specification call for a LSL=1.245mm and USL=1.255. What is the Cpk? You are a consultant to an manufacturing company that wants to design a control chart to monitor the parts quality sourced from a supplier. The supplier guarantees an average of only 4 blemishes per part. What is the three-sigma (standard deviation) LCL control chart limit (blemishes per part)? Over the...

1) The average female bobcat weight about 9.6 kg. Let's assume μ = 9.6 and σ = 1.75kg. a) Calculate Pr{Y > 11.5} b) Now assume you have a sample of n = 16 male bobcats. Calculate Pr{ Ȳ > 11.5}. c) Which probability is lower? Why? 2) Refer to problem 1. Now assume you take a sample of n = 9 male bobcats. a) What is the probability of the sample average being within 0.5 kg of the population...

Let's examine your ability to calculate NPV. Let's assume a piece of equipment has an implied discount rate of 8% and an initial cost of $1,000,000. The piece of equipment is expected to generate positive cash flows in years 1-3 of $150,000 and years 4-6 of $200,000 and $300,000 in year 7. Let's also assume that you have to spend $150,000 in year 4 in order to maintain this piece of equipment. What is the project's NPV? (ignoring income taxes)....

You are working on a manufacturing process that should produce products that have a diameter of 3/4 of an inch. You take a random sample of 35 products and find the diameter to be 13/16 of an inch with a standard deviation of 5/32 of an inch. 3. Calculate a 95% confidence interval around the sample mean. What do you notice about this interval relative to the desired diameter and how does this relate to your answers in questions 1...

You are working on a manufacturing process that should produce products that have a diameter of 3/4 of an inch. You take a random sample of 35 products and find the diameter to be 13/16 of an inch with a standard deviation of 5/32 of an inch. 1. Considering a t% level of significance, what can you state statistically about the process? Please include a null hypothesis, an alternative hypothesis, and use an appropriate test statistic (I.e. Zstat or Tstat).

Assume Y is a normally distributed population with unknown mean, μ, and σ = 25. If we desire to test H o: μ = 200 against H 1: μ < 200, (a.) What test statistic would you use for this test? (b.)What is the sampling distribution of the test statistic? (c.) Suppose we use a critical value of 195 for the scenario described. What is the level of significance of the resulting test? (d.) Staying with a critical value of 195,...

What is your dream school for completing your undergraduate degree? Let's assume for a moment that you received an admission letter from that school. However, you also realize that tuition and fees are extremely high. Would you accept the invitation to study at your dream school? Why or why not? Also, bring an example when you got deterred to purchase an item because the price was too high. What does this mean in terms of elasticity? What reasons made you...

Let's assume, for instance, that you are drawing a sample from a normal distribution with mean=0, and then you use t-test to assess whether the mean of the sample you just drawn is "significantly different" from zero. Then you repeat this procedure (draw-run t-test) many times. Will at least some of your samples (drawn from normal with known mean=0!) look significant? Why? Isn't p-value supposed to tell us good findings from the bad and true hypotheses from false ones? How...

Let's assume our class represents a normal population with a known mean of 90 and population standard deviation 2. There are 100 students in the class. a. Construct the 95% confidence interval for the population mean. b. Interpret what this means. c. A few students have come in. Now we cannot assume normality and we don't know the population standard deviation. Let the sample mean = 90 and sample standard deviation = 3. Let's make the sample size 20. We...
