True or False:
Suppose the Chi-Square test for independence is being used to test if two variables, erratic driving and cell phone usage, are statistically independent. A proper way to express the null and alternative hypotheses is as follows:
H0: Erratic driving and cell phone usage are independent
Ha: Erratic driving and cell phone usage are not independent

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
