Question

Find the population standard deviation of the set of data, to the nearest hundredth:

{10, 20, 30, 40, 50}
A)
10.00
B)
13.13
Eliminate
C)
14.14
D)
20.00

Answer 1

have you found the mu of this population

Answer 2

mu=30

Answer 3

10-30=-20-->(-20)^2=400
20-30=-10--->(-10)^2=100
30-30=0-->(0)^2=0
40-30=10---->(10)^2=100
50-30=20-->(20)^2=400

Answer 4

sum of squares: 1000

Answer 5

population variance:200

Answer 6

Population Standard Deviation: 14.14
