Question 1
1 / -0

In a series the number of times an item occurs is known as:

A
Number

B
Class frequency

C
Frequency

D
Cumulative frequency

Solution

The number of times a particular item is occurs in a class interval is called its frequency. For ex. in a table 10 has occurred 4 times then the frequency of 10 is 4.
Question 2
1 / -0

If the classes are $$0-10, 10-20, 20-30...$$ then in which class should the observation $$10$$ be included?

A
$$0 - 10$$

B
$$10 - 20$$

C
$$0 - 10$$ and $$10 - 20$$ in these $$2$$ classes

D
$$20 - 30$$

Solution

If the classes are $$0-10, 10-20, 20-30..,.$$ then the class in which the observation $$10$$ should be included $$10-20$$.
Hence, the correct alternative answer is (B).
Question 3
1 / -0

In an inclusive from of frequency distribution the true lower limit of a class is always obtained by subtracting :

A
$$1$$

B
$$1.5$$

C
$$0.5$$

D
None

Solution

In inclusive form, class limits are obtained by subtracting 0.5 from lower limit and adding 0.5 to the upper limit. Class size: Difference between the true upper limit and true lower limit of a class interval is called the class size.
Question 4
1 / -0

The upper limit of the class $$20 - 29 $$ is equal to :

A
$$2$$

B
$$29$$

C
$$22.5$$

D
$$29.5$$

Solution

In an interval $$a-b$$, the upper limit of the interval is $$b$$

So, in the interval $$20-29$$ , upper limit is $$29$$

Question 7
1 / -0

Select and write the appropriate answer from the given alternatives in each of the following sub-questions:
Let the p.m.f of a random variable X be

$$P(x) = \frac{3-x}{10}$$ for x = $$-1, 0, 1, 2 = 0$$
otherwise

Then E(X) is _______.

A
$$1$$

B
$$2$$

C
$$0$$

D
$$-1$$

Solution

$$P(x), pmf=\left.\{ \begin{matrix} \dfrac { 3-x }{ 10 } , & x=-1,0,1,2 \\ 0, & otherwise \end{matrix} \right. $$
$$E(x)=P(-1)+P(0)+P(1)+P(2)$$
$$E(x)=\left (\dfrac {3+1}{10}\right)+\left (\dfrac {3-0}{10}\right)+\left (\dfrac {3-1}{10}\right)+\left (\dfrac {3-2}{10}\right)$$
$$E(x)=\left (\dfrac {4+3+2+1}{10}\right)$$
$$E(x)=\left (\dfrac {10}{10}\right)$$
$$\boxed {E(x)=1}$$
