fiasKO [112]

Answer:

The standard deviation of the sample mean is $\sigma _ {\= x } = 2.711$

Step-by-step explanation:

From the question we are told that

The mean is $\= x = 60$

The standard deviation is $\sigma = 21$

The sample size is $n = 60$

Generally the standard deviation of the sample mean is mathematically represented as

$\sigma _ {\= x } = \frac{\sigma }{\sqrt{n} }$

substituting values

$\sigma _ {\= x } = \frac{ 21 }{\sqrt{60} }$

$\sigma _ {\= x } = 2.711$

Sarah currently earns $18.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 20% raise. How much wi

Pie

Answer:

21.6 $ / h

Step-by-step explanation:

Since it is a raise you'll calculate by multiplying the $ / h by (1 + % / 100)

In this case 1 + % / 100 = 1 + 20 / 100 = 1 + 0.20 = 1.20

1.20 * 18 = 21.6 $ / h

NB.:

If it was a decrease by 20 % => 1 - 20 / 100 = 1 - 0.20 = 0.80

You would multiply the $ by 0.80.
