Answer:
-19/2 or
-9 1/2
Step-by-step explanation:
-1/2 ÷ 1/19
Copy dot flip
-1/2 * 19/1
-19/2
-9 1/2
6x² + 12x - 21
3(2x² + 4x - 7)
2x² + 4x - 7 ⇒ This is the factorised answer
This is how you solve it:
Answer:
Step-by-step explanation:
Given that for a repeated measures study comparing two treatment conditions, an experiment was conducted.
n=9: Mean difference =4:
Variance = s^2 =36
Std error = ![\frac{s}{\sqrt{n} } =\frac{6}{3} \\=2](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%20%7D%20%3D%5Cfrac%7B6%7D%7B3%7D%20%5C%5C%3D2)
t statistic = Mean diff/SE
= ![\frac{4}{2} =2](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B2%7D%20%3D2)
