1 How do you calculate degrees of freedom for a Chi-Square test?

1 (#rows-1)(#columns-1) Home

How do you find the converse of an if, then statement p => q? 2 How do you find the converse of an if, then statement p => q?

Switch the hypothesis and conclusion: q => p 2 Switch the hypothesis and conclusion: q => p Home

3 If you have a Chi-Squared value of 2.34 and your critical value is 5.99, do you reject Ho and why?

No! Chi Square > critical value to reject. 3 No! Chi Square > critical value to reject. Home

How would you set this up to solve for x? 4 x How would you set this up to solve for x?

4 x2 = (400)2 + (375)2 – 2(400)(375)cos35 Home

5 If the Pearson correlation coefficient is –0.98, we say that the data has ______, ______ correlation. (2 words)

strong, negative correlation 5 strong, negative correlation Home
