Question

23) The mean of 9 observations is 24. Find the sum of the 9 observations​

Answer 1

Answer:

let sum of observation = x

mean=sum of observation / no. of observation

    24 = x/9

     24*9=x

     216=x

        x=216

Step-by-step explanation:

Answer 2

Answer:

Concept:

The average of a set of variables is known as the mean in mathematics and statistics. The geometric mean, the harmonic mean, and the plain arithmetic mean can all be used to calculate the mean. The mean of a probability distribution is the long-run mathematical average value of a variable with that distribution. The expected value of a random variable is indicated by (denoted).

Given:

The mean of 9 observations is 24. Find the sum of the 9 observations​

Find:

find the answer for the given question

Answer:

=> To find the mean, add all of the numbers in a set together and divide by the total number of numbers. The average of the numbers is the mean. To calculate, simply add all of the numbers together, then divide by the number of numbers. To put it differently, the sum is divided by the number of people.

given

$mean$ $= 24$

$Number$  $of$  $observations$ $=9$

$sum = N$

$mean = \frac{sum of all the terms}{number of observations}$

$24=\frac{x}{9}$

$x = 24*9$

$x = 216$

∴ $The$  $sum$ $of$ $the$ $9$ $observations$ $is$ $216$
