Q1// Magnetic resonance imaging (MRI) is a process that produces internal body images using a strong magnetic field. Some patients become claustrophobic and require sedation because they are required to lie within a small, enclosed space during the MRI test. Suppose that 20% of all patients undergoing MRI testing require sedation due to claustrophobia. If five patients are selected at random, using the binomial probability distribution formula, find the probability that the number of patients in these five who require sedation is a. exactly 2 b. none C. at least 4

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.

Q1/ Magnetic resonanee imaging (MRI) is a process that produces internal body
images using a strong magnetic field. Some patients become claustrophobic and
require sedation because they are required to lie within a small, enclosed space
during the MRI test. Suppose that 20% of all patients undergoing MRI testing require
sedation due to claustrophobia. If five patients are selected at random, using the
binomial probability distribution formula, find the probability that the number of
patients in these five who require sedation is
a. exactly 2
b. none
c. at least 4
