The ages of a group of 135 randomly selected adult females have a standard deviation of 18.3 years. Assume that the ages of fema

NeTakaya

Answer:

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student

Step-by-step explanation:

Here, we have

$n = \left (\frac{(z_{\alpha/2}) (\sigma) }{E} \right )^{2}$

Where:

n = Required sample size

σ = Standard deviation = 18.3

E = Margin of error = 1/2 year

$z_{\alpha /2}$ = Critical score from the confidence level = 1.645

Therefore,

$n = \left (\frac{(1.645) (18.3) }{\frac{1}{2} } \right )^{2} = 3624.88$

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.

In a football tournament, each team played exactly 19 games. Teams get three points for everyone and one point for every time. A

We can actually deduce here that when the tournament ended, team Olympus have tied for 13, 10, 7, 4, 1 times.

<h3>What is inequality?</h3>

In Mathematics, inequality is used to express or show quantities that are less than, greater than, greater than or equal to, less than or equal to.

The following can be seen in inequality expressions:

≤
≥
>
<
≠

Looking at the question, we can see that each team plays exactly 19 games.

Every win (w) = 3

Every tie (t)= 1

Every loose = 0

But Olympus got a total of 28 points

Thus: 3w + t = 28 ---------(1)

Note that each team plays 19 games

Thus, T + W ≤ 19 --------------(2)

and T , W ≥ 0

Looking at equation (1) and (2)

=> 2W ≥ 9

=> W ≥ 4.5

( match can be won in integers only )

=> W ≥ 5

W - 5, 6, 7, 8, 9

T - 13, 10, 7, 4, 1

Loose - 1, 3, 5, 7, 9

Thus, team Olympus have tied for 13, 10, 7, 4, 1 times.
