Generic drugs are lower-cost substitutes for brand-name drugs. Before a generic drug can be sold, it must be tested and found to perform equivalently to the brand name product. The U.S food and drug administration is now supervising the testing of the new generic antifungal ointment. The brand-name antifungal ointment is known to deliver a mean of 3.4 micrograms of active ingredient to each square centimeter of skin. As a part of testing, seven subjects apply the new generic antifungal ointment. Six hours later, the amount of drug that has been absorbed into the skin is measured. The amounts, in micrograms, for seven subjects are 2.6 3.2 2.1 3.0 3.1 2.9 3.7 with mean equals 2.9429 and standard deviation as 0.4995. Assume that the amount absorbed is normally distributed.

A pharmaceutical company fills a drug which is in a powder form into a bottle. It has an automatedprocess consisting of a filling machine and a sealing unit. After filling the bottle, it is automaticallysealed with a metallic cap. To monitor the quality of the process, samples of size 5 are drawnperiodically from the process and the quantity filled is measured. The table below has data on 12such observations.Sample 1 2 3 4 51 9.21 8.87 8.71 9.08 9.342 9.06 8.97 9.13 8.46 8.853 9.35 8.95 9.20 9.03 8.444 9.21 8.71 9.05 9.35 8.875 9.01 9.17 9.21 9.05 9.536 8.74 8.35 8.50 9.06 8.897 9.21 9.05 9.00 8.78 9.238 9.15 9.20 9.23 9.15 9.069 8.98 8.81 8.90 9.13 9.0510 9.03 9.10 9.26 9.44 8.4811 9.49 9.05 9.12 8.88 8.9312 8.95 9.10 9.02 9.04 8.96(a) Establish the upper and lower control limits for the X bar chart and the R Chart(b) Construct a control chart and investigate if the process is in controlValues for setting the control charts are A2 = 0.577, D3 = 0, D4 = 2.114
High cholesterol is one of the major risk factors for heart disease. A total cholesterol reading above 190 mg/dL is considered high.A physician is concerned that a patient may be at risk for high cholesterol. In order to accurately measure the patient's average cholesterol level, the physician instructs the patient to come into the physician's office once a week for 12 weeks for a blood lipid screening. The results of the 12 measurements are listed below. 189 186 199 197 190 186 185 200 200 200 185 190 Use the critical value method to test the hypothesis that the patient's cholesterol level is greater than 190 mg/dL, using a significance level of 10%. Assume that the distribution of all cholesterol measurements from this patient is approximately normally distributed. Determine the critical value(s) for this hypothesis test. Round the solution(s) to four decimal places. If more than one critical value exists, enter the solutions using a comma-separated list.Determine the test…

How Big Are Gribbles? Gribbles are small,pale white, marine worms that bore through wood.While sometimes considered a pest since they canwreck wooden docks and piers, they are now beingstudied to determine whether the enzyme theysecrete will allow us to turn inedible wood andplant waste into biofuel.24 A sample of 50 gribblesfinds an average length of 3.1 mm with a standarddeviation of 0.72. Give a best estimate for the mean length of gribbles, a margin of error for this esti-mate (with 95% confidence), and a 95% confidenceinterval. Interpret the confidence interval in context. What do we have to assume about the samplein order to have confidence in our estimate? 1. Find the upper and lower bound for this confidence interval.
