<h3><u>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</u></h3>

We are given that a cylinder shaped bucket is used as a sand container . We have to find how much sand it can hold , which can be found by knowing the volume of cylindrical bucket .The volume of a cylinder is given by :

$\quad\dashrightarrow\quad {\pmb{\sf {Volume = \pi r^2 h }}}$

where,

π = 3.14
r = 0.5 feet
h = 2.5 feet

$\quad\dashrightarrow\quad \sf {V =\pi r^2 h }$

$\quad\dashrightarrow\quad \sf { V = 3.14 \times 0.5^2 \times 2.5}$

$\quad\dashrightarrow\quad \sf {V = 3.14\times 0.5\times 0.5\times 2.5 }$

$\quad\dashrightarrow\quad \sf {V = 1.9625 }$

15. For a random sample of n = 64, find the probability of a sample mean being

mart [117]

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

$P(\bar x < 24.3)$

To find the probability first we have to determine the z score which is

$z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }$

= 1.92

Now probability is

$P(\bar x < 24.3) \\\\= P(z < 1.92)$

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered
