Alright here it goes, I'll give you my homework question, I forget what to use to answer the last part, part D (I've finished the other parts correctly)

1.) The Production manager at Landover Manufacturing wants an estimate of the time required by assembly-line workers to complete task A. The Followoing data REprestent the times in minutes by a random sample of six of the workers to complete the task.

14 , 17, 19, 21, 19, 15

a) Calculate the mean completion time

B)Calculate the median completion time

c)Calculate the standard deviation for the completion time

d)The Production manager also recorded times required by the workers to complete task B. The mean completion time was 640 minutes with a standard deviation of 1.10 minutes. Which task had greater variablility in completion time?

What do I use for D. Z-scores? Anyone know?..

oh man, I'll just get someone to help me out with that at school tommorow.

nvm I got someone on another board to do it for me. haha

man that stuff is easy i wouldve helped you if i was on in time

Yeah, I can figure that out. Might take a few days though, I'm pretty lazy when it comes to figuring stuff out.

yea my brain has gone to mush these days. only got 2 B's and one A on my last three tests that I wrote last week.

I m probably going to fail the stats test because this is just the basics of what we've been doing. I've missed over 3/4's of the classes this semester haha.

Man, I hear what you're talking about. You would think that during midterms the teachers would ease up on the homework. Surprise, they don't. I'm balls deep in fucking calculus, biology, chemistry, and economics right now. I'm only catching a break in english, because my prof is mad cool.

Yea I haven't had much of the homework problem. I just can't seem to concentrate on studying at all. Today I had 2 hours to just study for my stats or my finance midterm. Instead I was at the cafeteria for an hour talking to a guy I went to high school with and we were catching up. and then the next hour I went to the library and just blanked out. I'm really finding it hard to study.

My complaint would be that College is suppose to be more hands on, and yet we've only had tests and exams, I've had a total of 1 assignment due so far this semester, and it took me 20 minutes to do and I got 90%. It's absoloutly ridiculous. I haven't even studied for my finance midterm yet, and it's 100 multiple choice questions and it's tommorow. I just find it pointless for some reason.

Yeah, I'm fucked with my Biology midterm. I didn't take any highschool Biology, and I'm literally being thrown into the fire here. It's on Thursday, and my plan was to read through the textbook chapters like 3 times between now and then. I've gotten through half of it once so far. I'm finding it really hard to focus, because I really don't know what the fuck I'm reading about. Anyways, it's 40 multiple choice questions. My goal is an A. I'm really gonna have to strap down tomorrow night and get some reading done.

Damn DHB! Drawing my focus away!

if you need any help, i can do stuff from highschool biology

Oh man that really sucks ass. For me I can't study because all this shit is getting to easy for me. For 2nd year college it's still some pretty basic stuff... I didn't pay to learn about things I already fucken knew about :(

and yea DHB is defenitly a distraction.
