Question

If mean and sun of n observation is 5 and 50, find n

Answer 1

Hey folk !!

Here's the answer you are looking for

$mean \: = \: \frac{sum \: of \: observations}{number \: of \: obserations}$

Here, in the question,

number of observations = n

Sum of the observations = 50

and Mean = 5

So,
$5 = \frac{50}{n} \\ \\ n = \frac{50}{5} = 10$

Therefore, n is 10.
