Answer:

$-\frac{4}{3}$

Step-by-step explanation:

We are given that

$5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})$

We have to find the value of given expression

$\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})$

$=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}$

$=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}$

LCM(2,3,6)=6

$=\frac{32-25-15}{6}$

$=\frac{32-40}{6}$

$=\frac{-8}{6}$

$=-\frac{4}{3}$

Answer:

The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For the population:

Mean 2 mm, standard deviation 0.04 mm

Describe the sampling distribution of X (for a sample of size 16).

Sample of size 16 means that $n = 16$

By the Central Limit Theorem, approximately normal with mean 2 and standard deviation $s = \frac{0.04}{\sqrt{16}} = 0.01$
