in 175 words What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications? (Hint: Use Excel’s =BINOMDIST() function to find the probability.)
Homework Answers
In excel you just copy the following function
=BINOMDIST(175,175,0.95, FALSE)

A quality control engineer is in charge of testing whether or not 90% of the DVD players produced by his company conform to specifications. To do this, the engineer randomly selects a batch of 12 DVD players from each day's production. The day's production is acceptable provided no more than 1 DVD player fails to meet specifications. Otherwise, the entire day's production has to be tested. (i) What is the probability that the engineer incorrectly passes a day's production as...

Problem 3 A manufacturer has four classifications (A, E, LL, and V) for its components. A batch of 100 components is expected to be populated with 45, 25, 4, and 26 of components A, E, LL, and V, respectively. The company is interested in carrying out quality control measures on their products by randomly sampling a certain number of products from each batch. What is the smallest sample size that can be used by the manufacturer to...

The Methodical Pharmaceutical Company is trying to a new product that is supposed to detect a certain substance that is banned in athletic competition. Among 83 subjects with positive tests results there were 6 false positives (indicating that they had used the banned substance when they in fact had not); among 57 subjects with negative tests results, there were 2 false negative results (indicating they had not used the banned substance when in fact they had). How many subjects are...
