Answer 5

@jim_thompson5910

Answer 6

i think its A

Answer 7

I would agree since A has a smaller IQR, so the values are closer together

Answer 8

Find the values of the 30th and 90th percentiles of the data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152

A. 30th percentile = 105; 90th percentile = 200

B. 30th percentile = 113; 90th percentile = 200

C. 30th percentile = 105; 90th percentile = 176

D. 30th percentile = 113; 90th percentile = 176

Answer 9

i know its not C

Answer 10

first sort the data values

Answer 11

100, 100, 105, 113, 129, 132, 146, 152, 176, 200

Answer 12

ok now multiply 0.3 by 10 to get 0.3*10 = 3

so the value in slot #3 is the 30th percentile

Answer 13

i tried calculating it and i think its B

Answer 14

0.9*10 = 9

the value in slot 9 is the 90th percentile

Answer 15

it's not B

Answer 16

ok

Answer 17

Explain

Answer 18

just did, re-read my last 2 posts

Answer 19

???

Answer 20

multiply 0.3 by 10 to get 0.3*10 = 3

so the value in slot #3 is the 30th percentile

-------------------------------------------------------

0.9*10 = 9

the value in slot 9 is the 90th percentile

Answer 21

C is the wrong option

Answer 22

i got it wrong

Answer 23

oh...hmm

Answer 24

i think 100 is the repeating figure so we can count it as 1

Answer 25

maybe, the annoying thing about percentiles is that there is actually more than one way to do it

Answer 26

there's no set standard, which is frustrating

Answer 27

i mean 100 written just one times may be we can get the correct answer

Answer 28

if we do this it will be D

Answer 29

for some reason, I want to exclude 200 as the 90th percentile, so that's why I'm leaning towards 176 as the 90th percentile

Answer 30

yeah D is the next plausible answer choice

Answer 31

Identify the sampling method. You want to find how many students use public transportation. You interview every fifth teenager you see exiting a movie theater.

you're welcome, so is this a stats class you're in?

Answer 38

Answer 39

hmm interesting, i've never had stats mixed in with algebra before

Answer 40

Find the values of the 30th and 90th percentiles of the data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152

A. 30th percentile = 105; 90th percentile = 200

B. 30th percentile = 113; 90th percentile = 200

C. 30th percentile = 105; 90th percentile = 176

D. 30th percentile = 113; 90th percentile = 176

Answer 41

iam rearranging them i think i sort them out wrong

Answer 42

we did this one already??

Answer 43

100, 100, 105, 113, 129, 132, 146, 152, 176, 200

Answer 44

are you sure its D

Answer 45

that one doesn't work either?

Answer 46

because if we count 100 as the figure written once then we will get B as an answer

Answer 47

B was already eliminated though remember?

Answer 48

no its was C

Answer 49

C doesn't work, so it has to be D

Answer 50

we eliminated B too because there's no way the 90th percentile is 200

Answer 51

jim the answer was b i was right we will be counting 100 as it is written once

Answer 52

@jim_thompson5910

Answer 53
