7. a number of minor automobile accidents occur at various high-risk intersections in teton county despite traffic lights. the traffic department claims that a modification in the type of light will reduce these accidents. the county commissioners have agreed to a proposed experiment. eight intersections were chosen at random, and the lights at those intersections were modified. at the .01 significance level, is it reasonable to conclude that the modification reduced the number of traffic accidents?

step-by-step explanation:

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
