71. As a newly appointed marketing manager of a firm, you have been asked to determine if a special Point-of-Purchase (POP) display causes the purchase of the product on display. What type of research design will be needed?

Correct Answer: (c) Experimental
Solution:"Experimental research design" can be understood as a collection of research designs to understand different causal processes through manipulation and controlled testing.

During its course, the researcher tries to maintain control over all factors that may affect the result of an experiment. This way, the researcher attempts to determine or predict what may occur.

72. Exponential distribution comprises which of the following characteristics?

A. It is discrete distribution
B. It is a family of distributions
C. It is skewed to the left
D. The x values range from zero to infinity

Which one of the following options is most appropriate ?

Correct Answer: (d) (b) and (d)
Solution:Exponential distribution comprises the following characteristics :-

It is a family of distributions
The x values range from zero to infinity.

73. The correlation coefficient is the _____ of two regression coefficients.

Correct Answer: (a) Geometric mean
Solution:The correlation coefficient is equal to the geometric mean of two regression coefficients. The positive and negative sign of correlation coefficient depends on the sign of regression coefficients.

r= ±√byx . bxy
where byx, bxy are regression co-efficient and r is correlation coefficient.

74. Which of the following modules is NOT a part of a typical ERP system?

Correct Answer: (a) The Corporate Management (CM) Module
Solution:ERP System includes assets management, Human resources and project system module but not corporate management module.

75. Read the following regarding PERT and СPМ:

A. PERT is probabilistic in nature and СРМ is deterministic in nature.
B. PERT is most suitable for new as well as old projects but CPM is of great value for projects that are repetitive.
C. PERT focuses primarily on time element and attaches lesser significance to the cost. On the contrary, the CPM puts strong emphasis on cost.
D. PERT is activity-oriented and CPM is event-oriented.

Which one of the following options is most appropriate

Correct Answer: (d) (a) and (c)
Solution:PERT is a probabilistic in nature and CPM is deterministic in nature. (c) PERT focuses primarily on time element and attaches lesser significance to the cost on the contrary, the CPM puts strong emphasis on cost.

76. Which of the following statements is true?

Correct Answer: (b) The Pearson correlation coefficient is designed to capture the extent of linear association between variables
Solution:The True statement is "The Pearson correlation coefficient is designed to capture the extent of linear association between variables.

77. Which of the following statistical techniques should be used when you wish to examine the association between two nominal variables?

Correct Answer: (c) Chi-square contingency test
Solution:The chi-square test provides a method for testing the association between row and column variables, in a two way table.

78. Respondents of a recent sample survey provided name of friends they thought would be likely users of a new product. These friends were contacted, completed a survey, and asked to supply names of other likely users. Which method of sampling has been used in this survey?

Correct Answer: (b) Snowball
Solution:Snowball sampling is a non-random sampling technique where in the initial informants are approached who through their social network nominate or refers the participants that meet the eligibility criteria of the research under study. So, this method is also called as the referral sampling method or chain sampling method.

79. Indicate the correct answer for the combination from the following regarding the conditions for the applicability of a binominal distribution:

A. There are n independent trials
B. Each trial has only two possible outcomes
C. The probabilities of two outcomes do not remain constant
D. The trials are independent

Which of the following options is correct?

Correct Answer: (c) (a), (b) and (d)
Solution:(a) There are n independent trials
(b) Each trial has only two possible outcomes
(d) The trial are independent.

A binominal distribution has two mutually exclusive outcomes and the probability of these outcomes remains constant from trial to trial.
