Instructions

For the following questions answer them individually

Question 141

The arithmetic mean of 28, 32, 34, 24, 42, 46, 38, 36 is

Video Solution

Solution

The given data is $$28, 32, 34, 24, 42, 46, 38, 36$$

Number of records=8

The arithmetic mean of the given data $$\dfrac{28+32+34+24+42+46+38+36}{8}=35$$

Question 142

The median of 18, 16, 18, 12, 10, 14, 16 is

Video Solution

Solution

As per the question,

18, 16, 18, 12, 10, 14, 16

Now arranging the data in the increasing order$$=10, 12, 14, 16, 16,18, 18$$

Total number of observations =7

Hence, the $$median =\dfrac{n}{2}+1$$

$$\Rightarrow median=4^{th} terms =16$$

Question 143

The mode of the following frequency distribution is

Video Solution

Question 144

The standard deviation of 6, 7, 8, 9, 10 is

Video Solution

Question 145

The standard deviation of any three consecutive integers is

Video Solution

Question 146

If $$d_i$$ stands for the difference of ranks and if $$\sum_{i = 1}^n d_i^2 = \frac{(n - 1)n(n + 1)}{8}$$, then the value of the
coefficient of rank correlation is

Video Solution

Question 147

A problem in Mathematics is given to three students A, B and C whose chances of solving it are $$\frac{1}{3}, \frac{1}{4}$$ and $$\frac{1}{2}$$ respectively. What is the probability that the problem will be solved by at least one of them?

Video Solution

Question 148

If a card is drawn at random form a well shuffled pack of 52 cards, then the probability that it is a spade or a king is

Video Solution

Question 149

The probability that a non-leap year has 53 Mondays is

Video Solution

Question 150

A and B are two sets such that n(A) = 3 and n(B) = 2. If a relation from A to B is selected at random, then the probability that the relation will be a function is
