Standard Deviation, σ: 1.5
Count, N: 10
Sum, Σx: 15
Mean, μ: 1.5
Variance, σ2: 2.25
Steps
σ2 =
Σ(xi - μ)2
N
=
(0 - 1.5)2 + ... + (5 - 1.5)2
10
=
22.5
10
= 2.25
σ = √2.25
= 1.5
Answer:
Step-by-step explanation:
The point will be 2 on the x-axis and 5 on the y axis.
The pH scale is used in real life to measure liquids that we drink and use everyday such as orange juice, bleach, pepsi, liquids,soap and fruit punch the pH scale affects us because it tells us how acidic or basic the liquid is that is being put into your body
No.
Examples:
