Re: CSIR NET Mathematical Sciences Previous Paper

As you want previous year Mathematical Sciences question paper of CSIR National Eligibility Test (NET) so here I am giving you the same, please have a look…….

CSIR UGC - NET: Mathematical Sciences Previous Papers (Solved) and 25 Practice Sets
by Dhipragya Dubey

1. An unknown number N of taxis plying in a town are supposed to be erially
numbered from 1 to N. If the n different taxis you have come across in the town can
be assumed to form a simple random sample with replacement, find an unbiased
estimator of the total number of taxis in the town. Also find the variance of your
estimator.

2. Show that in a randomized block design the estimates of the elementary block and
treatment contrasts are orthogonal observational contrasts.

3. Suppose in a 25–factorial experiment with factors A, B, C, D and E, a replicate is
divided into four blocks of size eight each. How many effects will be confounded?
Is it possible to confound the effects AB, BC and ABC? Justify your answer.

4. The daily demand for a commodity is approximately 100 units. Every time an order
is placed, a fixed cost of Rs.10,000/- is incurred. The daily holding cost per unit
inventory is Rs.2/-. If the lead time is 15 days, determine the economic lot size and
the reorder point. Further suppose that the demand is actually an approximation of a
probabilistic distribution in which the daily demand is normal with mean µ = 100 and
s.d. σ = 10. How would you determine the size of the buffer stock such that the
probability of running out of stock during lead time is at most 0.01?

5. A physiological disorder X always leads to the disorder Y. However, disorder Y may occur by itself. A population shows 4 % incidence of disorder Y. Which of the following inferences is valid?

4% of the population suffers from both X & Y
Less then 4% of the population suffers from X
At least 4% of the population suffers from X
There is no incidence of X in the given population

6. Diabetic patients are advised a low glycaemic index diet. The reason for this is

They require less carbohydrate than healthy individuals
They cannot assimilate ordinary carbohydrates
They need to have slow, but sustained release of glucose in their blood stream
They can tolerate lower, but not higher than normal blood sugar levels

7. Standing on a polished stone floor one feels colder than on a rough floor of the same stone. This is because:

Thermal conductivity of the stone depends on the surface smoothness
Specific heat of the stone changes by polishing it
The temperature of the polished floor is lower than that of the rough floor
There is greater heat loss from the soles of the feet when in contact with the polished floor than of the rough floor

8. If the atmospheric concentration of carbon dioxide is doubled and there are favorable conditions of water, nutrients, light and temperature, what would happen to water requirement of plants?

It decreases initially for a short time and then returns to the original value
It increases
It decreases
It increases initially for a short time and then returns to the original value

9. To examine whether two different skin creams, A and B, have different effect on the human body n randomly chosen persons were enrolled in a clinical trial. Then cream A was applied to one of the randomly chosen arms of each person, cream B to the other. What kind of a design is this?

Completely Randomized Design
Balanced Incomplete Block Design
Randomized Block Design
Latin Square Design
