Question 1] Find the mean for each set of data6,9,2,4,3,6,5

SOVA2 [1]

Given:

The given set of data is

$6,9,2,4,3,6,5$

To find: The mean for the given set of data?

Explanation:

We can calculate the mean of a given set of data by using the formula

$Mean=\frac{Sum\text{ of the terms}}{Number\text{ of terms}}$

Here,

We can calculate the sum of terms as

The sum of terms = 6+9+2+4+3+6+5

The sum of terms =35.

and

The number of terms = 7.

Now, by substituting the value in the above formula

Therefore,

$\begin{gathered} Mean=\frac{35}{7} \\ \\ Mean=5 \end{gathered}$

Hence, the mean = 5.

Answer: The mean for a given set of data is 5.

Irina-Kira [14]

Answer:

The interquartile range(IQR) is 31.

Step-by-step explanation:

Given:

A distribution has the five-number summary shown below:

24, 36, 42, 57, 65.

Now, to find the interquartile range (IQR).

So, to get the IQR we need to find the quartile 1 and quartile 3:

As, 42 is the median.

Quartile 1 is the average of first half.

24, 36, 42, 57, 65.

Q1 = $\frac{24+36}{2}$

Q1 = $\frac{60}{2}$

Q1 = $30$

Quartile 3 is the average of last half.

24, 36, 42, 57, 65.

Q3 = $\frac{57+65}{2}$

Q3 = $\frac{122}{2}$

Q3 = $61$

Thus, by putting the formula we get IQR:

IQR = Q3 - Q1.

$IQR=61-30$

$IQR=31.$

Therefore, the interquartile range(IQR) is 31.
