Question

Calculate the mean for samples for which the sample size and summation from nothing to nothing x∑x are given below.
a. nequals=​10, summation from nothing to nothing x∑xequals=8282
b. nequals=​16, summation from nothing to nothing x∑xequals=336336

Answer 1

In order to compute the mean, simply divide the sum over the number of 
element in the sample, like this:
1)$\frac{\Sigma x_i}{10}= \frac{8282}{10}= 828.2$

2)
$\frac{\Sigma x_i}{10}= \frac{336336}{16}=21021$

Answer 2

Answer:

100
