The following are the average weekly losses of work-hours due to accidents in 10 industrial plants before and after a certain safety program was put into operation: 45 and 36, 73 and 60, 46 and 44, 124 and 119, 33 and 35 57 and 51, 83 and 77, 34 and 29, 26 and 24, 17 and 11 Can we say with 95% confidence that the new safety program made a difference in the mean weekly loss of work-hours due to accidents? You can assume that the difference in the average weekly losses of work-hours roughly follows a normal distribution. Justify your answer.

4.0 ft

step-by-step explanation:

4.0 ft

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
