skewed to the right

normal (approximately)

Answer 2

i got two more after this

Answer 3

i have no idea what this means, sorry

Answer 4

Why is sampling without replacement acceptable with a large population?

When a large sample is take from a large population, the sample retains the characteristics of the original distribution.

When a small sample is taken from a large population, the samples maintain their independence.

When a sample without replacement is taken, there is no requirement to maintain the same sample size.

When a sample without replacement is taken, the samples will have the appropriate amount of data.

Answer 6

Samples of size n = 15 are randomly selected from the population of numbers (0 through 9) produced by a random-number generator, and the standard deviation is found for each sample. What is the distribution of the sample standard deviations?

skewed to the left

skewed to the right

not enough information provided

normal (approximately)

Answer 7

Answer 8

I have no earthly idea what these questions are asking :|

Answer 9

You ask some hard to understand questions x.x

Why is sampling without replacement acceptable with a large population?

Then again there is not enough information provided option... purhaps that is what your supposed to push? O_o

Answer 16

either that or normal (approximately)... but I can't see it being the others...

Answer 17

Hmm...

Answer 18

Well those are 2 options... but they may be wrong so erm. Good luck? x.x

sorry ._.

Answer 19

at this point it's testing reasoning and not math skills LOL
