T-Test Numbers 1.3

T-TESTS

I unfortunately do not have the Excel Packet so after a few deep breaths into a brown paper bag I slowly made my way through this assignment.

I used the video to work the problems step by step and came up with the answers which are posted here.

I am used to Hypothesis, Null Hypothesis, T-Tests and standard deviations thanks to my stats class as an undergrad.  It has been a while since I had to do the actual math.  As a teacher we are given tests and the work is done for us.
I watched the video that shows you how to do the T test.

Hypothesis:
H1 Null: There is no correlation between White and Black Scores.
H1: There is a correlations between White and Black test scores.

H2 Null: There is no correlation between White and Hispanic Scores.
H2: There is a correlations between White and Hispanic test scores.

H3 Null: There is no correlation between Black and Hispanic Scores.
H13 There is a correlations between Black and Hispanic test scores.

It is apparent that through the results of the t-test, there is a significant difference between the three ethnic groups when looking at reading scores.  Ethnicity does impact the scores.
