Penicillin is produced by the Penicillin fungus, which is grown in a broth whose sugar content must be carefully controlled. Several samples of broth were taken on three successive days, and the amount of dissolved sugars, in milligrams per milliliter, was measured on each sample. The results were as follows.

A metal company is supplying its product to a manufacturer of washing appliances that has specified that the outside diameter be 0.255 + 0.028 inch. Fifty samples of n = 5 units show that the process is in good statistical control, the diameters are normally distributed, and that μx and σx for the process are 0.260 and 0.02 inch, respectively. a) What percent of the product made by this process is within the specifications? Answer in 2 decimal placesb) If the process variability was reduced by about half (i.e., σx changed to 0.01 inch), what percent of the product made by this process is within the specifications? Answer in 2 decimal places.
Step 2: Determine if r is statistically significant at 0.01 and 0.05 levels.
Calculate the average values of the Cp and Cpk capabil-ity indices for the BOD data , assuming that LSL=5 mg/L and USL=35 mg/L. Do these val-ues of the indices indicate that the process performance is satisfactory?
(a) Calculate a 95% two-sided CI for the true average bond strength. (b) Calculate a 95% two-sided CI for the proportion of all such bonds whosestrength values would exceed 10. show major intermediate steps.
What is the RPI index? How can the defective product rate of a production process be determined by using the RPI index? The average distribution range of 2 samples consisting of 4 units is R = 10.8 mm. The tolerance limit is plus – minus 10 mm. Calculate the RPI and evaluate if it will reject. What happens to the reject situation if the tolerance limit is plus-minus 20 mm?
A study was done to compare the flu incidence rates at the sart and at the end of winter of a given year. A sample of 100 persons were asked for incidence of flu twice: once at the start and once at the end of winter. Sample data were as follows: a. Give 99% CI for the difference in flu incidence rates at the start and at the end of winter? b. Compute a measure of association between flue incidence at the start and at the end of winter?
Indicate the most appropriate statistical analysis method for situations a - d below. a) Measurement of blood pressure in 4 groups of patients. b) Measurement of cholesterol before and after a patient has taken a drug to lower cholesterol. Ie. 2 measurements on each patient. (c) Comparison between the number of persons who have or do not have a disease of the circulatory system and their diet classified into one of three categories: vegetarian, mixed meat and vegetables and most meat. d) Measurement of how much weight affects the concentration of glucose in the blood.
