If Brooklyn College students have an IQ of 100, on average, with a standard deviation of 16 points, and I collect 48 BC Psycholo

Anastaziya [24]

Answer:

1 $\mu = 100$

2 $\sigma = 16$

3 $\mu_x = 100$

4 $\sigma _{\= x } = 2.309$

Step-by-step explanation:

From the question

The population mean is $\mu = 100$

The standard deviation is $\sigma = 16$

The sample mean is $\mu_x = 100$

The sample size is $n = 48$

The mean standard deviation is $\sigma _{\= x } = \frac{\sigma }{\sqrt{n} }$

substituting values

$\sigma _{\= x } = \frac{16 }{\sqrt{48} }$

$\sigma _{\= x } = 2.309$
