Answer:
3.60
Step-by-step explanation:
Data provided in the question:
level of significance = 0.05
Sample size , n = 25 observations
correlation coefficient, r = 0.60
Now,
The test statistic to compute whether the population correlation is zero is given using the formula :
t =![\frac{r\sqrt{n-2}}{\sqrt{1-r^2}}](https://tex.z-dn.net/?f=%5Cfrac%7Br%5Csqrt%7Bn-2%7D%7D%7B%5Csqrt%7B1-r%5E2%7D%7D)
on substituting the respective values, we get
test statics , t = ![\frac{0.60\times\sqrt{25-2}}{\sqrt{1-0.60^2}}](https://tex.z-dn.net/?f=%5Cfrac%7B0.60%5Ctimes%5Csqrt%7B25-2%7D%7D%7B%5Csqrt%7B1-0.60%5E2%7D%7D)
or
t = 3.5968 ≈ 3.60
No, if two lines are parallel then they will have NO solutions, because they DO NOT intersect. Parallel lines have the same slope and different y-intercepts, therefore making them not intersect.
