ICS Part 1 Statistics English Medium Chapter 9 Short Questions Preparation

Question # 1

Describe the application of the binomial distribution.

Ans 1: The binomial distribution is applicatble to a wide variety of practical problems as well as to problems of an artificial sort, such as those dealing with cards, dice, coins and coloured balls in boxes.
Ans 2: It can be applied to any industrial situation where an outcome of a process is dischotomous and the results of the process are independent with a probability of success beng the same from trial to trial.
Ans 3: It is also used in medical and military situations. A drug eigher curse or does not cure the disease. A missible either hits or does not bit the target.

Question # 2

State the properties of the hyperogemoetric experiment.

Ans 1: 1- Each trial of the hypergeometric experiment results in an outcome that can be classified into one of the two categories, success or failure.
Ans 2: 2- The successive trials are dependent.
Ans 3: 3- The probability of success changes from trial to trial.
Ans 4: 4- The experiment is repeated a fixed number of times.

Question # 3

Define hypergeometric random variable.

Ans 1: The random variable X which represents the number of successes in a hypergeometric experiment is called a hypergeometric ranodm variable, it is a dscrete variable which can assume any of the values x = 0,1,2,....... n,

Question # 4

Write down any two properties of hypergeometric probability distribution.

Ans 1: 1.The outcomes of each trail may be classified into to categories : success or failure.
2.The successive trail are dependent.

Question # 5

What is the mean and variance of binomial distribution.

Ans 1: Mean -nP
Variance -nPq

Question # 6

What is the range of the binomial random variable.

Ans 1: The range of the binomial random variable is 0 to n.

Question # 7

What are the resembling point in binomial and hypergeometric experiments.

Ans 1: 1.The outcomes of trail may be classified into two categories as success or failure.
2.Experiment is repeated a fixed number of times.

Question # 8

What is a hypergeometric experiment.

Ans 1: An experiment in which a random sample is selected without replacement from a finite population is called a hypergeometric experiment. Here the successive trials are not independent and the probability of success does not remain the same from one trial to the other.

Question # 9

Define hypergeometric experiment.

Ans 1: An experiment in which a random sample is chosen without replacement from a finite population is said to be hypergeometric experiment.

Question # 10

Identify the parameters of the binomial distributiion b( x; n,p) and the hypergeometric distribution h( x;N,n,h)

Ans 1: The binomial distribution b (x; n,p) has two parameters n and p, whereas the hypergeometric distribution h ( x; N; n,k) has three parameters N, n and h
