In the above problem, assume that probability of an item being defective is 0.1. Then in a random sample of 60 such items, how do you apply continuity correction to calculate the probability that at least 5 items are defective? a. P(X is at least 5)=P(X<5.5) b. P(X is at least 5)=P(4.54.5) d. P(X is at least 5)= P(X>5) What are the mean and standard deviation of the binomial in the problem above? a. 6 and 2.32 b. 6 and 5.4 c. 5.4 and 2.32 d. 5.4 and 1.52
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.
In the above problem, assume that probability of an item being defective is 0.1. Then in a random sample of 60 such items, how do you apply continuity correction to calculate the probability that at least 5 items are defective?
a. P(X is at least 5)=P(X<5.5)
b. P(X is at least 5)=P(4.5<X<5.5)
c. P(X is at least 5)= P(X>4.5)
d. P(X is at least 5)= P(X>5)
What are the mean and standard deviation of the binomial in the problem above?
a. 6 and 2.32
b. 6 and 5.4
c. 5.4 and 2.32
d. 5.4 and 1.52
