**Correct Answer : C**

**Explanation : **

With 3 points we can describe a polynomial of degree 2 .

so our desired polynomial is of the form y=ax^{2 }+ bx + c.

plugging the above given values in the above quadratic equation we get

5 = a x 0 + b x 0 + c

=> c = 5.

6 = a x 1 x 1 + b x 1 +c

=> 6 = a+ b + c

but c = 5

so a + b = 1

also

8 = a x 2 x 2 + b x 2 +c

8 = 4a + 2b + 5

but a+b = 1 using this we get

b = 1/2 , a = 1/2, also c = 5

using these values we get value for P(3) as:

(1/2) x 3 x 3 + (1/2) x 3 +5

9/2 + 3/2 +5 = 1

The ordinal scale places events in order, but there is no attempt to make the intervals of the scale equal in terms of some rule. Rank orders represent ordinal scales and are frequently used in research relating to qualitative phenomena. A student`s rank in his graduation class involves the use of an ordinal scale. One has to be very careful in making statement about scores based on ordinal scales.

## Mean score = 40

mean=sum of observation /no of observations

sum of observations = mean * no of observations

that is 40 x 100 = 4000

after replacement, sum of new observation = 4000 - 83 + 53 = 3970

mean of new observation = 3970 / 100 = 39.7

mean=sum of observation /no of observations

sum of observations = mean * no of observations

that is 40 x 100 = 4000

after replacement, sum of new observation = 4000 - 83 + 53 = 3970

mean of new observation = 3970 / 100 = 39.7

**Correct Answer : A**

**Explanation : **

Mean = Total sum/Number of observations

Total = 99 x 55 = 5445

Let the mean of the 100th item be y, then according to question

(((99 x 55) + y) / 100) + 99 = y

5445 + y + 9900 = 100y

15345 = 99y

y = 15345 / 99

y = 155
