LBC NEEDS STATISTICS HELP ASAP!

[LongBeachCoupe]

Hey guys, I am in a real bind here... My girlfriend needs a homework for her intro to statistics class done correctly or she isnt going to pass her class, and as a result wont receive her MBA ontime... I will have the questions shortly and I will be scanning them and posting them here..

If you are competent in basic statistics (z scores and things of the such) please chime in here, or email me...

Theres a set of chrome hood dampners and a set of my overlays available as payment or we can work something else out...

PLEASE HELP!

[ThatGuyRoger]

i got a B+ in intro stats last semester, but we did alot of work out of SPSS and a more sociological concept of stats

[headhunt3r]

Post the questions here if you can, and I'll see what I can do. It's been a long time since I've done my stats course but I'll help if I can.

[SHIFT_COUPE]

Damn Brian, overlays for stats help? Whats next? :p

[LongBeachCoupe]

Ok now mind you i need the work for this.. so id need it scanned n sent to me... The first 3 questions i have done.. the rest i have NO CLUE...

LBC im a member of smarthinking.com they have online tutors for every subject. if you want ill let you use my account.

[LeroyBrown]

there are tutors on there i think 24.7 f

[LongBeachCoupe]

Well this is a 2 week class shes taking, its over after she gets this done, and a homework that shes getting tomorrow done...

Im sure a tutor would help, but shes a 4th grade teacher and isnt really good at math nor interested in learning it much lol...

Will the tutors literally do the work???

practically yes lol. as long as she knows a little about the subject, theyll help her figure it out.

[LeroyBrown]

so do you want it bro?

[LongBeachCoupe]

yes, i emailed you...

If anyone else can help out though, im ready to pay up!

#7 is A

thats all i can do.....

[LeroyBrown]

yes, i emailed you...

sent you all the info

[ThatGuyRoger]

so this is from the best of my knowledge and from my notes and such from the previous semester.

you have the first 3 answers so:

4) A the formula goes: Standard Deviation=(6-7.67)^2+(6-7.67)^2+(1-7.67)^2+(8-7.67)^2+(12-7.67)^2+(13-7.67)^2/6 that will give you your variance (rounded to the nearest hundreth)5)C that is the square root of the variance (rounded to the nearest hundreth)6)E7)A8)C9)D10)0 formula 100-100/511) -2 formula 90-100/5

for 12 and 13 i couldnt figure out, but if you're good in algebra where you can rearragen the formula to find X the formula for Z score is X-mean/standard deviation

14)80 maybe?15)016)A17)?18)B19)A formula 6000-12000/300020) as for the distribution...not sure how you can explain, i thought it was a positive distribution

i hope it helps, if you know someone that can double check those so they are 100% right. b/c i'd hate for you to fail due some of my wrong answered or uncertainty.

i dont have a scanner but i hope you understood spme of the work i tried to showgood luck!

If you still need help after tonight I can go through it tonight at home - I just have to whip out the stat book from 3 years ago and I can get it done - I was a stat beast.

[Marisha]

here's what i ended up with:

4) a5) c6) e7) a8) c9) d10) 011) -212) 112.513) 92.514) 415) 016) a17) c18) b19) a20) skewed to the right (median < mean)

formulas used :variance (sigma^2) = (sum (x-mean)^2)/number of elementsstandard deviation (sigma) = square root of variancez score = (x - mean) / standard deviation

[LeroyBrown]

LEE-RoOOYMy girlfriend is a graduate student, shes just finished all her classes (special education, elementary ed), and to pass NYS regulations she needed to take this class.. After this test is completed, the only other thing she has to do is go to a "conference" discussion once a week then shes done!

She has told me "im never going back to school again after this" lol, so I dont think shes going to wind up using the service, although we both greatly appreciate it!

[headhunt3r]

Hmm... I assume the stats is done and over with?

Sorry I missed helping out.

[LongBeachCoupe]

All done fellas... she (hopefully) did great... ill post her scores when we get em back!
