The mean is given by:
The variance is given by:
Therefore the variance is 30698.6
That means multiplying the two fractions, but to do so, lets first convert the whole part to fraction as well, and remember that to multiply fractions you multiply numerator times numerator and denominator times denominator as well:
1 3/4 = 1 + 3/4 = 4/4 + 3/4 = 7/4
150 1/2 = 150 + 1/2 = 300/2 + 1/2 = 301/2
therefore:
<span>1 3/4 of 150 1/2
</span><span>= (1 3/4)(150 1/2)
= (7/4)(301/2)
= (7*301)/(4*2)
= 2107/8
that is the result</span>
