1 Sample T-Test
The parameters of this 1 sample T-test.
What is...
µ is the true mean rating AP Statistics students give to the AP Statistics class on a scale from 1 to 10 (10 being they love the class).
The definition of a type 1 error for this 1 sample T-test.
What is...
We reject the null hypothesis when the true mean rating AP Statistic students give to the AP Statistics class is ≥5
The null and alternative hypothesis of the Chi-Square test.
What is...
Ho: There is no association between AP Statistic's students rating of and grade in AP Statistics
Ha: There is an association

What is ∑(observed-expected)2/expected
The probability of a type 2 error
What is 0.99?
The T-Test equation.
What is...
