According to a candy company, packages of a certain candy contain 1616% orange candies. Suppose we examine 100100 random candi

GaryK [48]

Answer:

a) By the Central Limit Theorem, 16%.

b) 0.0367 = 3.67%

c) We expect 16% orange candies, give or take 3.67%.

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

For samples of size n of a proportion p, the expected sample percentage is p and the standard error is $s = \sqrt{\frac{p(1-p)}{n}}$

In this problem, we have that:

$p = 0.16, n = 100$

a. What value should we expect for our sample percentage of orange candies?

By the Central Limit Theorem, 16%.

b. What is the standard error?

$s = \sqrt{\frac{0.16*0.84}{100}} = 0.0367$

0.0367 = 3.67%

c. Use your answers to fill in the blanks below. We expect ____% orange candies, give or take _____%.

We expect 16% orange candies, give or take 3.67%.

Find the surface area of the cylinder in terms of pi

tia_tia [17]

Answer:

Step-by-step explanation:

The area of a cylinder is A=2πrh+2πr^2

You first do the first problem of the equation (A=2πrh)

You fill in the radius and height ( A=2π(4)(8) )

You first multiply 4 x 8 = 32. ( A=2π(32) )

Then you multiply 2 x 32 = 64. ( A=π(64) )

Then you multiply π x 64 (using 3.14 for π) = 200.96 m^2

You then do the second part of the equation. (A=2πr^2)

You fill in the radius. (A=2π(4)^2)

Then multiply 4 x 4 = 16 (because it's to the power of 2 [4 times itself twice]) and then multiply it by 2.

16 x 2 = 32. ( A=π(32) )

Next you just multiply 32 x π (using 3.14 for π again) = 100.48 m^2.

Then you just add them together:

200.96 m^2 + 100.48 m^2 = 301.44 m^2

So <u>301.44 m^2</u> is your answer.

(I hopefully think it is.)

ADD is to MULTIPLY as SUBTRACT is to what

Rzqust [24]

Divide! If you add three and four, you get seven. Subtracting four from seven, you get three. If you multiply three and four, you get twelve. If you then divide by four, you get back to 3. I hope this helped!
