Large-scale integrated (LSI) circuit chips are made in one department of an electronics firm. These chips are incorporated into analog devices that are then encased in epoxy. The yield is not particularly good for LSI manufacture, so the AQL specii ed by that department is 0.15 while the LTPD acceptable by the assembly department is 0.40. a. Develop a sampling plan. b. Explain what the sampling plan means; that is, how would you tell someone to do the test?

A new screening test for thyroid cancer was administered to 1,000 adult volunteers at a large medical center complex in Europe. The results showed that 152 out of 160 diagnosed cases of thyroid cancer were correctly identified by the screening test. Also, of the 840 individuals without thyroid cancer, the screening test correctly identified 714. Base on this information, calculate the test's: 1. Sensitivity 2. Specificity 3. Positive predictive value 4. Negative Predictive Value 5. Accuracy 6. Prevalence rate. Please help with 4,5,6. I have attached 1,2,3.

Cindy is a server at a local restaurant who makes, on average, $58 in tips per daytime shift. Cindy thinks she will make more if she moves to the nighttime shift. Her manager will choose five random nighttime shifts for Cindy to work. Cindy plans to conduct a significance test on the hypotheses H0: mu = 58; Ha: mu > 58 at the alpha = 0.05 level, where  is the true mean amount of tips Cindy will make working nighttime shifts. Are the conditions for performing the test met? No, the 10% condition is not met. No, the sample size is too small, and a Normal distribution cannot be assumed. Yes, all conditions are met for performing a significance test about the mean. Yes, only the random condition must be met in order to perform a significance test. No, there is no way the manager could choose a random sample of shifts to work.

What does brand loyalty mean to​ consumers? According to a recent research​ report, 38​% of consumers associate trust with brand loyalty. Complete parts​ (a) through​ (e) below.       a. To conduct a​ follow-up study that would provide 95​% confidence that the point estimate is correct to within ±0.04 of the population​ proportion, how large a sample size is​ required?   A sample size of 566566 consumers is required. ​(Round up to the nearest​ integer.) b. To conduct a​ follow-up study that would provide 99​% confidence that the point estimate is correct to within ±0.04 of the population​ proportion, how many people need to be​ sampled?   A sample size of 978978 consumers is needed. ​(Round up to the nearest​ integer.) c. To conduct a​ follow-up study that would provide 95​% confidence that the point estimate is correct to within ±0.02 of the population​ proportion, how large a sample size is​ required?   A sample size of 22632263 consumers is…
