Samples of 20 parts from a metal punching process are selected every hour. Typically, 1% of the parts require rework. Let X denote the number of parts in the sample of 20 that require rework. A process problem is suspected if X exceeds its mean by more than 3 standard deviations. (a) If the percentage of parts that require rework remains at 1%, what is the probability that X exceeds its mean by more than 3 standard deviations? (b) If the rework percentage increases to 4%, what is the probability that X exceeds 1? (c) If the rework percentage increases to 4%, what is the probability that X exceeds 1 in at least one of the next five hours of samples?

A statistical process control chart example. Samples of 25 parts from a metal punching process are selected every hour. Typically, 1% of the parts require rework. Let X denote the number of parts in the sample of 25 that require rework. A process problem is suspected if X exceeds its mean by more than three standard deviations Round your answers to four decimal places (a) If the percentage of parts that require rework remains at 1%, what is the probability...
. Samples of 20 products from a production line are selected every hour. Typically, 2% of the products require improvement. Let X denote the number of products in the sample of 25 that require improvement. A production problem is suspected if X exceeds its mean by more than 3 standard deviations. (a) If the percentage of products that require improvement remains at 2%, what is the probability that X exceeds its mean by more than 3 standard deviations? (b) If...
A factory manufactures 2000 metal parts per day. Samples of 20 parts are selected every hour. On average, 1% of the parts are faulty. Let X denote the number of parts in the sample of 20 that are faulty. What is the probability that X exceeds its mean by more than three standard deviations? O 0.132 O 0.001 0.182 0.0169
A binomial distribution has p=o.22 and n=98. Use the normal approximation to the binomial distribution to answer parts a through d. a. what are the mean and standard deviation for this distribution? b. what us the probability of exactly 16 successes? c. what is the probability of 14 to 25 successes? d. what is the probability of 12 to 20 successes?
The normal-curve approximation can also be used for discrete distribution other than the binomial distribution. For instance, it is reasonable to use this approximation if the Poisson distribution has a parameter greater than 30. This approximation uses as the mean and as the standard deviation. Suppose that the number of false alarms received weekly by the fire department of a large city follows a Poisson distribution with = 45. In any given week, find the probability that a) There will...
solve this problem by using Binomial approximation and compare the results with answers from Hypergeometric (2 Bookmarks) Problem Show all steps: ON Suppose that 50 sites on a patient might contain lesions. A biopsy selects 8 sites randomly (without replacement). What is the minimum number of sites with lesions so that the probability of at least one selected site contains lesions is greater than or equal to 0.95? Rework for greater than or equal to 0.99. Step-by-step solution Step 1...

X~binom(10,0.45) Question 4. An inequality developed by Russian mathematician Chebyshev gives the minimum percentage of values in ANY sample that can be found within some number (k21) standard deviations from the mean. Let P be the percentage of values within k standard deviations of the mean value. Chebyshev's inequality states...
