Answer:

μ = 6500

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes 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 a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The average game is attended by 6,500 fans, with a standard deviation of 450 people.

This means that $\mu = 6500, \sigma = 450$

35 games:

This means that $n = 35$

Distribution of the sample mean:

By the Central Limit Theorem, we have $\mu_x = \mu = 6500$ and the standard deviation is:

$\sigma_x = \frac{450}{\sqrt{35}} = 76$

Part B:53%
Part C:F > H, 80 dislike orange juice while 65 dislike apple juiceThis means the people surveyed dislike orange juice more.

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 cent

Kaylis [27]

Answer:

4021.2 cm³

Step-by-step explanation:

you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start

the formula for finding the volume of a cylinder is πr² · h

so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...

which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³

A jar contains 3 red, 2 white, and 1 green marble. Aside from color, the marbles are indistinguishable. Two marbles are drawn at

IRISSAK [1]

Answer:

0.6

Step-by-step explanation:

A permutation is an arrangement of outcomes whereas a combination is a grouping of outcomes.

Order matters in case of permutations but does not matter in combinations.

Given:

Number of red marbles = 3

Number of white marbles = 2

Number of green marbles = 1

To find: probability of picking 4 marbles and getting one of each color

Solution:

Total number of outcomes = $6_C__4$ = $\frac{6!}{4!\,2!}=\frac{6\times 5\times 4!}{4!\times 2}=15$

Number of favourable outcomes = 2 red, 1 white and 1 green marble + 1 red, 2 white and 1 green marble = $3_C_2\,2_C_1\,1_C_1+3_C_1\,2_C_2\,1_C_1$ = $\frac{3!}{2!\,1!}\times \frac{2!}{1!\,1!}\times 1+\frac{3!}{2!\,1!}\times 1\times 1=6+3=9$

So, probability of picking 4 marbles and getting one of each color = Number of favourable outcomes/Total number of outcomes = $\frac{9}{15}=\frac{3}{5}=0.6$
