I am having difficulty setting up a Excel sheet for the following problem.
An industrial Engineer at ABC Products wants to determine whether there are more units produced on PM shift then AM Shift.
Sample of 54 Am workesr with a mean number of units produced is 345 with a standard deviation of 21.
Sample of 60 PM workser with a mean number of units produced is 351 with a standard deviation of 28 units.
Significance level is .05
Trying to figure out if the PM shift is larger.
I have a data set based on an uneven distribution of cards in a 60 card deck, each with a value ranging from 0-5.
I need to build a probability distribution of all the random samples of 10. So, how many random sets of 10. have an average value of 1 (or a total of 10) etc.
Then, I need to build a variable distribution so that it changes as I change the sample size. So, with a sample of 20 cards, what does the distribution look like?
Can this be done in excel? Should I post what I have now to work with?
Morning All,
Does anyone know of a free tutorial that can explain how to get statistical data in Excel? - I have seen it done before (in excel) for 'Linear regression', I am wondering if the same can be done for "Polynomal"?

Hi Lords and Ladies!
I was wondering if there are any statistical tools in excel?
What I need is a comparison program to do the following:
Column A: abcdefgh
Column B: bcaghfrnreo
Column C: 80% match (roughly)
Is that possible to do in excel?

Hi everyone, first thanks for the help.
I am trying to create a histogram and let me explain some of the data.
I have a list of data separated like so:
3.5
3.6
3.8
3.8
3.9
3.9
etc...
Now I need to calculate the frequencies of these like so:
3.5 (up to but not including) 4.0
4.0 (up to but not including) 4.5
I can count out the frequencies myself but i need to create a histogram (bar graph) with the y axis as the frequency and the x axis as the IMR(infant mortality rate: ie the 3.5 (up to but not including) 4.0).
I am having problems with calculating the frequencies because when setting the bin values because they include 4.0.
If this is confusing I can provide some more information, but cannot find a good tutorial that would create a histogram anywhere remotely close to the histogram i drew by hand.
Hi,
I was hoping someone could help me with this particular statistics+excel problem that I cannot solve, or, at least need some confirmation that I am solving it correctly...
MY DILEMMA: Let's say I am asking people to choose their favorite letter(s) ranging from a-vvv (1-100). I ask 9 people to choose their favorites, but they can't choose more than 100 #'s (obviously since a-vvv represents 100 letters). Once I gather the information, the only way I know how to create the proper order is to AVERAGE the data by inputting zero into the fields/letters that were not chosen (since no one chose all 100 letters). My question is... HOW DO I PROPERLY ORDER THE "LETTERS" FROM MOST TO LEAST POPULAR BASED ON THE SUBMISSIONS??? I realize this is a statistics problem, but I'm hoping something efficient can be done in excel.
I've also attached the working excel file to use as a working document. Feel free to PM if you would like to attach an excel file.
Thanks in advance everyone!

I have the following problem for my stats class and I am trying to figure out which statistical formual I need to use to get the answer. Please advice! Any help will be much appreciated.
A sample of salaries finds sample mean $35 thousand and sample variance 81. If the population mean is to be estimated within $2 thousand (that is, $2 thousand above and $2 thousand below), how many employee salaries must be sampled? Assume 95% confidence and t-multiple = 2.
Hi
Been working a lot in excel lately and now my workbook is quite big, with an incredible about of formulas and references...
Would love to find a program or function that can list a lot of statistics about a file, such as number of formulas, references, cells, whatever...
Does anybody know of such a function?
Big Thanks in advance for that help!
Mike
