  • How do I calculate the probability of Z-Score 4?

    Ok I know that the probability of a Z-score of 4 is .49997. I simply want to find out HOW this number was calculated from a Z-score chart that only goes up to like 3.49.

    Z-score charts typically only go up to 3.4 and 3.49, so how do I find the probability of a Z-score equaling 4?

    *NOTE* this is finite math. please be descriptive as possible and refrain from statistics and calculus solutions.

    much thanks!

  • Finite math problem. Large Z-score and finding probability?

    Hi ok my instructor has been skipping around in the book and I'm confused how to find the probability for an area above a very high Z-score.

    Ok heres the problem:

    "Weights of people riding an elevator from a population with MEAN=160 pounds and VARIANCE=400(SD=20). If a 4600-pound load will crash the elevator, find the probability that a random sample of 30 people will crash."

    OK now what I did, is found: n=30, STANDARD ERROR OF THE MEAN=3.651483717, and VARIANCE OF SAMPLE=13.33.

    Next i found that since the MEAN was 160 pounds, and the RAW SCORE was 4600 pounds(the breaking point for the elevator).=, I computed in the Z-Score formula and got a large Z-score of 1215.944078.

    Ok, presuming I calculater correctly. Ok how do I find the probability of a score that high when the Z-chart only goes up to like 4.39 I believe.

    I feel that something may have been left out of the lesson plan with all of this skipping around in the book. Please note that I have not had calc or statistics or anything, so please use lingo and notations appropriate for FINITE math. Thank you.

  • How can I get over my girlfriends past?

    My girlfriend and I have been dating for 6 months. I met her through some roommates when I transferred colleges and we pretty muck instantly connected.

    She is 21 and recently finished culinary school and is looking for work. She plans on going back to school after she works in the field for a while. Myself, I am a full time student.

    Ok, now I have only been with 6 girls. She on the other hand has been with 35 guys. She admitted this, not proudly, admitting to the majority of them back when she was in high school. She use to be on drugs, hang with male "friends" and party...a lot. The good thing is that the majority of this stopped like a few years ago. just within the past few years shes only been with like 5 dudes.

    I guess I just feel like WTF. How can someone just switch off and on like this and whats keeping her from resorting back to that whoreish lifestyle. I guess she has learned alot from her past. I just feel It would put a tremendous amount of pressure on me to keep her entertained enough to hold her attention from promiscuity like that, or even factors that lead to it like drugs. Like i mentioned, I should probably breath comfort in Knowing that this **** stopped nearly 2 years before she even knew I existed, So i guess perhaps I should chill. I know she did have one long term relationship in high school and she cheated on him but felt bad..... but again this is when she was like 16 or 17 and drunk. Not very committed at the time. She says now that she didn't want to live like that anymore and wanted to change , so I guess I should respect that and try my best to forget her past. Im not a saint or anything having cheated on my EX.

    A few more details: she was gang raped at 15 and was very heavily into drugs(coke)... so there is some definite abuse issues that she had to sort out=(. I was abused too and was on drugs so I can relate to many of the same things. Also note that she use to drink mass amounts hard-a and smoke weed all day, wheres now she drinks and smokes weed on occasion like everybody else in this town. I figure the change has a lot has to do with her learning from her mistakes, maturing and growing as a person. I want to trust her and I genuinely do as she is very level headed and intelligent at this point in her life.

    I'm just wondering If what I feel is normal. Is what I feel justified? How can I stop obsessing over her dead past since its obviously poisoning a good relationship that we both care a great deel about. Sorry about the spelling and grammar. I got no sleep lastnignt because this stuff was stressing me out.

  • Do flat warts on face go away?

    Hi I have had small freckle like discolorations on my face for about a year and they get worse when I shave. Its hard to tell that I have them simply because they are on the beard line and neck, so it basically just looks like a permanent 5'o'clock shadow.

    I've read that you cary the virus for life but your body's immune system will eventually clear you up as the virus gets beat down into suppression. I'm wondering If there is a treatment for them available, preferably over the counter. Ive heard a few mentions of Imiguimod and Salicylic acid, but I would love for someone to confirm this. Perhaps anybody in the medical/ beauty field, or someone who knows from experience.

    Thanks

  • Why do the pics from iphone show up as blanks on my PC after I save them from my email.?

    Ok, I'll send a pic from my iphone to my email. Next I'll open that email on my PC laptop(windows7). I see the picture perfectly in the email but when I save the pic to my pictures, It simply saves it with no thumbnail. Basically the picture is just a blank white square located in my pictures. Other pictures Ive saved from online or uploaded from my camera are clearly visible, but the ones sent to my email via iphone only save and appear as a blank white picture.

    ok, all the info on how to do this is out of date since the new privacy settings have happened. I thought I had my list hidden, but I just requested to be friends with someone and he said he was able to see my list. There was drama in the past, and I simply want my list to be visible to nobody but myself.

    I am a horrible speller. I'm in college with dyslexia and could use something like this. What i am looking for is something that allows me to make word lists of problem words that I usually spell wrong. This would also help with words that sound alike but are spelled compleatly different.

    I still have a problem with "Weather" & "Whether"

  • Is it "Pointless" to take German?

    I must do a year of foreign language in college.

    My brother(spanish major) insists that spanish is the best rout and that German is pointless.

    Now, I have a real F***ing problem with that. I like German. I listen to German music, drive a German car, my mom lived there until age 14, and I generally like the uniqueness of the culture. FACT: Germany is the worlds 3rd largest economy<<buisness majors*hint hint*.

    I feel that the Uniqueness of It, is what makes it interesting and magnetic. why always take the road more traveled traveled?

    I can now understand why SOME people in Europe dislike the attitude of SOME Americans have. I mean christ, There is more out there than friggin English and Spanish speaking immigrants. Theres a whole world out there... So many people with their head up their a##.

    So I just wanted your thoughts. Should I take German? Do you feel this would be "pointless"? I'm going to take German reguardelss... but your thoughts on this would be awesome, and much appreciated=)

  • Does FB randomly delete certain friends?

    I now see one less friend on my friends list. It is a good friend, and I even saw them today. I noticed on my wall, that every post that I've had liked and commented on by this person is now empty... like they never existed. Now, I know that they didn't block me because when I search for the person, I see the profile picture..... but when i click on the profile, the loading screen just goes on forever. haha this and the fact that we actually know each other and, have for ever.

    I think ive had this happen before with people. It could be just a bug, or maybe my friends profile is messed up and will re-appear as a friend tomorrow.. idk? It sucks when all the stuff posted and liked by them on my wall just vanishes like they never existed you know. hmmmm
