a. What is the probability that on a given day, fewer than 890 O-rings meet the specification? b. Find the 60th percentile of the number of O-rings that meet the specification. c. If the machine operates for five days, what is the probability that fewer than 890 O-rings meet the specification on three more of those days?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
A machine produces 1000 steel O-rings per day. Each ring has
thickness specification.
a. What is the probability that on a given day, fewer than 890 O-rings meet the specification?
b. Find the 60th percentile of the number of O-rings that meet the specification.
c. If the machine operates for five days, what is the probability that fewer than 890 O-rings meet the
specification on three more of those days?
