1. what is the standard deviation for the following set of numbers?
2.4.5.5.6,8
a. 2.35
c. 1.54
b.3.67
d. 1.80

D. 1,80

Step-by-step explanation:

To solve this first we need the formula for standar devation

s=sqrt((n(∑x²)-(∑x)²)/n(n-1)

Then we need ∑x and ∑x²

∑x=2+4+5+5+6,8=22,8

∑x²=2²+4²+5²+5²+6,8²=116,24

s=sqrt((5(116,24)-(22,8)²/5(5-1)

s=sqrt(3,058=

s=1,75=1,8

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
