Or a population, N = 10,000, μ = 121, and σ = 21. Find to 2 decimal places the z value for

Ugo [173]

Answer:

The z value is - 2.88

Step-by-step explanation:

The formula of the z-score of a population is z = (x¯ - μ)/(σ/ $\sqrt{n}$ )

The given in the problem is:

μ = 121
σ = 21
x¯ = 112.35
n = 49

Let us substitute all of these values in the rule above

$z=\frac{112.35-121}{\frac{21}{\sqrt{49}}}$

Simplify up and down

$z=\frac{-8.65}{\frac{21}{7}}$

$z=\frac{-8.65}{3}$

z = - 2.883333

Round it to 2 decimal places

∴ z = - 2.88

The z value is - 2.88
