A process has a mean of 9 grams and a standard deviation of 0.25 grams. The lower spec limit is 8.00 grams and the upper spec limit is 10.00 grams. - Compute Cp. - What is the probability the process will operate within the specification limits? - P{out of spec} for Wonderdisk - μ = 10, σ = 2.3 qP{X ≤ 6 or X ≥ 12} qP{8 ≤ X ≤ 13}
For a normal population with an average of 60 and a standard deviation of 12 what is the probability of selecting a random sample of 36 scores with a sample mean greater than 64? p(M greater than 64)? a 50% b .9772 or 97.72 % c. .8777 or 87.77% d. .0228 or 2.28% A population has a mean of 50 and a standard deviation of 5, find the z-score that corresponds to a sample mean of M=55 for a sample...
A coffee company sells bags of coffee beans with an advertised weight of 454 grams. A random sample of 20 bags of coffee beans has an average weight of 457 grams. Weights of coffee beans per bag are known to follow a normal distribution with standard deviation 4 grams. (a) Construct a 95% confidence interval for the true mean weight of all bags of coffee beans. (Instead of typing ±, simply type +-.) (b) Provide an interpretation of the confidence...
The average weight of an apple is 185 grams with a standard deviation of 13 grams, with an approximately Normal distribution. How many grams above average is Christopher’s apple? How many standard deviations above average is Christopher’s apple? What percent of apples weigh less than Christopher’s? What percent of apples weigh more than Christopher’s? David has an apple that is 1 standard deviation below average weight. What is the weight of David’s apple? What percent of apples weigh less than...
C&A is making steel rods with an average diameter of 1 mm. The process has a standard deviation of 0.2 mm. The upper and lower specification limits are 1.2 mm and 0.8 mm respectively. What is C&A’s process capability index?

A marathoner is now running his marathons with an average time of 3 hours, and 15 minutes, and a standard deviation of 15 minute and her times follow a normal distribution. What is the probability of the marathoner running a marathon time of exactly 2 hours and 58 minutes? 0.00 0.05 0.15 0.12 Which of the following would indicate a process has special causes of variation? A point is above the lower control limit and below the upper control limit...
Write a program that computes the average and standard deviation of four scores. The standard deviation is defined to be the square root of the average of the four values. Use two functions. One function to calculate the average, this function should be with Return Type "double". Second Function should be to calculate standard deviation, this function should be with Return Type "void". Allow the program to continue until the user tells the program he/she is finished. This is for...
Product filling weights are normally distributed with a mean of 365 grams and a standard deviation of 19 grams. a. Compute the chart upper control limit and lower control limit for this process if samples of size 10, 20 and 30 are used (to 2 decimals). Use Table 19.3. For samples of size 10 UCL =| LCL For a sample size of 20 UCL = LCL For a sample size of 30 UCL = LCL = b. What happens to...
Joe's computer chip production yields chips with an average life of 1800 hours and a standard deviation or sigma of 100 hours. The tolerance upper and lower specification limits are 2400 hours and 1600 hours. What is the Cp? What is the Cpk?
