No programming please. I don’t want a code as an answer. We would like to compare two semiconductor manufacturing processes. Suppose that thenumber of open circuits on a semiconductor wafer follows Poisson distributions withrates of (for process 1) and 22 (for process 2). A sample of 250 wafers was collectedfrom each process and the total number of open circuits detected in samples 1 and 2 are800 and 900, respectively.Develop a large-sample hypothesis test to check if both production processes have thesame defect (open circuits) rates (Assume a=0.05)

To test if both production processes have the same defect rates, we can use the Poisson distribution…

The variability in the amounts of impurities present in a batch of chemical used for a particular process depends on the length of time the process is in operation. A manufacturer using two production lines, 1 and 2, has made a slight adjustment to line 2, hoping to reduce the variability as well as the average amount of impurities in the chemical. Samples of 25 and 25 measurements from the two batches yield 1.04, respectively 0.51 variances. Do the data present sufficient evidence to indicate that the process variability is less for line 2? Use 5% significance level. Conduct a hypothesis test of the airline executive’s belief. [α = 0.05]
The following table shows the results of two random samples that measured the average number of minutesper charge for AA Lithium-ion (Li-ion) rechargeable batteries versus Nickel-Metal Hydride (NiMH)rechargeable batteries. Perform a hypothesis test using α =0.05 to determine if the average number ofminutes per charge for Li-ion batteries last longer than NiMH batteries. Assume the population variances forthe number of minutes per charge are unequal.Li-ion NiMH110 8798. 9290 9087. 8992 89101 8898 8788 9187 9299 86100. 88103 9089 92105 90909781 1)State the hypotheses. 2) Compute the test statistic and Compute the p-value. 3) Make the decision and Summarize the results.
A study was conducted by a group of neurosurgeons. They compared a dynamic system (Z-plate) and a static system (ALPS plate) in terms of the number of acute postoperative days in the hospital spent by the patients. The descriptive statistics for these data are as follows: for 14 patients with dynamic system, the sample mean number of acute postoperative days was 7.36 with standard deviation of 1.22; for 6 patients with static system the sample mean number of acute postoperative days was 10.5 with sample standard deviation of 4.59. Assume that the numbers of acute postoperative days in both populations are normally distributed. We wish to estimate µ1 − µ2 with a 99 percent confidence interval. Can you assume unknown population variance are equal. a. Degrees of freedom and t-value are b. Margin of error and confidence interval are c. Based on your interval in part (b), we can state with 99 percent confidence that the average numbers of acute postoperative days in two populations i.…
