I need help with solving this problem: Find the value of E, the margin of error, for c=0.90, n=10 and s= 3.7
Thanks!

Find the z score that corresponds to .90 confidence interval and plug and chug.

I have rainfall data of some stations. I have also normals of rainfall for these stations. I want to perform Trend Analysis, Statistical significance, Kurtosis etc. on this data. I am giving example of data of a sation.

How about a t score. :-)

Vizaya, it would be nice if you would start your own thread for your own problem. It would also be nice if you didn't post it three times - that is unnecessary.
