Where do you find the statistic symbols like mu or the u with a line symbol on the computer for statistics?

galactus · Mar 22, 2009, 03:52 PM

Do you mean like this?:

${\mu}, \;\ \overline{u}, \;\ \overline{x}, \;\ {\pi}, \;\ {\omega}, \;\ {\theta}$

Yes, those are the symbols? Can you pay someone to assist you with your statistic assignments. This is my last class in a doctoral program and I am totally lost. I understood how to do the historgrams and charts but this I cannot comprehend.

This is very basic stuff if you are just learning how to read a z-table. What seems to be the

Trouble? This is for a doctoral program and you've not seen this somewhere along the way?

You have hypothesis testing to get to.

Do you have a good stats book? If not, I recommend Elementary Statistics by Larson.

It is very well written and has lots of examples.

I am sure you can find someone in your area to tutor you face-to-face.

I used to teach stats. But I am not there. Someone in person would be best for you.

What is the probability if a z-score will be greater than 1.96?

wplummer · Mar 23, 2009, 08:00 PM

It is amazing that I have come this far and not had any difficulty with my math courses. I understood the class work on histograms and charts. It was fairly simple once I seen the data, but as a visual learner, this part of the class is a little difficult.

The course book is Statistics by Wendy J. Steinberg. I also have statistics for the utterly confused by jaisingh.

It appears that of the 8 students in the class, only 2 understand what we are doing. The others express equal frustration in completing our assignments. By the way, the two are math and business students. The rest of us are education and leadership in education majors.

Thanks

Look up 1.96 in the z table. The value given in the table comes from the left. So, to find the

probability > 1.96, subtract from 1. You should see the prob. That corresponds to 1.96 is

.975. 1-.975=.025. Note, that the score that corresponds to .025 is -1.96.

This just comes off a graph. The z scores come from negative infinity, So, when they ask for

a >, subtract from 1.
