Question

the mean of 41,43,48,42,47,is​

Answer 1

Answer:

1st add all the obs..

ans will come of sigma x as 221

than divide by total obs... i.e.,n=5

221/5=44.2

Answer 2

Given:

41,43,48,42,47

To Find:

The mean

Solution:

The mean is defined as the average of the values, which is calculated by dividing the sum of observations by a total number of observations. It is denoted by the x bar. The formula for mean is,

$\bar x=\frac{\sum x_i}{n}$

Now the observations are 41,43,48,42,47 and a total of 5 observations, now finding the value of mean by using the formula,

$\bar x=\frac{41+43+48+42+47}{5}\\ =\frac{221}{5} \\=44.2$

So the mean is 44.2.

Hence, the mean of the given observations is 44.2.
