Answer:

2

Solution,

Given data: 3,7,8,10,X

Summation FX= 3+7+8+10+X= 28+x

N(total number of items)= 5

Mean= 6

Finding the value of X,

[tex]mean = \frac{summation \: fx}{n} \\ or \: 6 = \frac{28 + x}{5} \\ or \: 6 \times 5 = 28 + x \\ or \: 30 = 28 + x \\ or \: - x = 28 - 30 \\ or \: - x = - 2 \\ x = 2[/tex]

The value of X is 2.

Hope this helps...

Good luck on your assignment...
