The wood flooring manufacturers association claims a new product restores a high-gloss finish to old wood floors. a gloss meter is used to measure the shine of a wood floor, and a highgloss finish should have a rating of at least 80 units. to check the manufacturer’s claim, the sealer and finish were applied to 35 randomly selected wood floors and the gloss was measured after each application dried. the sample mean gloss was x 5 78.6. assume s 5 3.45. is there any evidence to suggest that manufacturer's claim is false?

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
