Ninety of the samplestudents are in the Business College, 120 are in theLiberal Arts College, and 90 are in the EducationCollege.
This problem is an example of a

a.) normallydistributed variable
b.)test for independence
c.)Poisson distributed vaiable
d.)multinominal population

The problem is an example of d.) multinomial population

Step-by-step explanation:

A multinomial distribution is type of probability distribution that describes the distribution of more than two variables.

The properties of a multinomial distribution are:

In the case provided the variables are:

X = number of students in Business college

Y = number of students in Arts college

Z = number of students in Arts college.

The researcher wants to know if the proportion of the variables X, Y and Z has changed or not.

This is an example of multinomial distribution and the population is a multinomial population.
