Answer:
Formulas
Step-by-step explanation:
Formulas are all unique and share the common trait of "x" and "y" values and a common purpose of helping you find the x and y value and/or answer to your question.

Answer:
173/1000
Step-by-step explanation:
I believe the problem ask for s which is the standard
deviation. We must recall that the formula for z statistic is stated as:
z = (x – x over bar) / s
Where,
z = z statistic = 2.5
x = sample value or sample score = 102
x over bar = the sample mean or sample average = 100
s = standard deviation = unknown
Rewriting the equation in terms of s:
s = (x – x over bar) / z
Substituting the given values into the equation:
s = (102 – 100) / 2.5
s = 0.8
Therefore the standard deviation s is 0.8
