Rival:

ight

Rival:

idk this yet srry

ChrisTheFlash:

do u know the answer?

ChrisTheFlash:

what is the answer

ChrisTheFlash:

bruh its multiple choice all i need is an answer.

Katrin369:

It's a multi choice answer right?

Katrin369:

Well there is only one answer.

ChrisTheFlash:

what is it?

Katrin369:

So, what can we eliminate?

ChrisTheFlash:

yes

Katrin369:

Hint: A distribution is skewed if one of its tails is longer than the other.

ChrisTheFlash:

im just gonna guess

Katrin369:

So,

Katrin369:

Okay, what do you think?

ChrisTheFlash:

i think it is b

Katrin369:

@christheflash wrote:

Not quit. B is symmetrical.

Katrin369:

And so is C.

Katrin369:

And so is A.

Katrin369:

So you're left with D.

ChrisTheFlash:

wait i thought about it i think it is a or c

ChrisTheFlash:

what about this problem

Katrin369:

A and C are symmetrical. A skewed distribution is not symmetrical.

So the answer is D.

ChrisTheFlash:

memeXpapi:

?

Katrin369:

Okay,

Katrin369:

Lets eliminate 2 options.

ChrisTheFlash:

a and c

Katrin369:

Okay correct

Katrin369:

Why are you eliminating them?

ChrisTheFlash:

umm i just feel like i should

Katrin369:

@christheflash wrote:

So you don't know?

Katrin369:

Okay Then I will

Katrin369:

Can you tell me what is symmetric distribution?

ChrisTheFlash:

ummm i think In statistics, a symmetric probability distribution is a probability distribution and assignment of probabilities to possible occurrences—which is unchanged when its probability density function

Okay

Katrin369:

Now, what do you think the answer is?

ChrisTheFlash:

still no

ChrisTheFlash:

wait

ChrisTheFlash:

its b

Katrin369:

@christheflash wrote:
its b
Great job! You're correct. Now,that you found out what is symmetric distribution,

Katrin369:

Can you tell my why you eliminated A and C?

ChrisTheFlash:

this is also i have a problem

Katrin369:

Are there graphs to this question?

ChrisTheFlash:

no

Katrin369:

Okay. Can you explain what is "bell curve"?

ChrisTheFlash:

a bell with curves :D

Katrin369:

Lol no

ChrisTheFlash:

A bell curve is a graph depicting the normal distribution, which has a shape reminiscent of a bell. ... Its standard deviation depicts the bell curve's relative width around the mean. Bell curves (normal distributions) are used commonly in statistics, including in analyzing economic and financial data.

Okay. what does it look like? If there was a plot graph what would it look like?

I mean like symmetrical left line longer right line longer

ChrisTheFlash:

this is a bell curve

Katrin369:

Okay.

Katrin369:

Okay there has to be a plot graph read the question.

ChrisTheFlash:

Katrin369:

This is a different question.

Katrin369:

Okay lets solve this question.

ChrisTheFlash:

can we hurry i have a meeting in 15 minues

ChrisTheFlash:

i have this question too

Katrin369:

First, find out how do you find the median. Next, find out how do you find the range. Then, find out how do you find the mode. Finally, find out how do you find the mean. Then, we will solve E.

Katrin369:

Let me know if you need help with A-D.

ChrisTheFlash:

just tell me wht e is

I'm sorry, I can't tell you. I can only help you.
