Step-by-step explanation:

-2.1 = 2.5z - 2.6

-2.1 + 2.6 = 2.5z

0.5 = 2.5z

0.5/2.5 = z

5/25 = z

1/5 = z

0.2 = z

Set {0.2}

-2.1 = 2.5z - 2.6

-2.5z = -2.6 + 2.1

-2.5z = -0.5

z = -0.5 ÷ (-2.5)

z = 0.2

Stels [109]

Answer:

The appropriate response is "0.9476".

Step-by-step explanation:

The given values are:

Standard deviation,

$\sigma=1150$

Randomly selected railroad-car shipments,

n = 500

As we know,

⇒ $\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }$

On substituting the values, we get

⇒ $=\frac{1150}{\sqrt{500} }$

then,

⇒ $=P(-1.94$

⇒ $=P(Z$

On using the table of P, we get

⇒ $=0.9738 - 0.0262$

⇒ $=0.9476$
