A new process for producing a type of novolac resin is supposed to have a mean cycle time of 3.5 hours per batch. Six batches are produced, and their cycle times, in hours, were 3.45 3.47 3.57 3.52 3.40 3.62. Can you conclude that the mean cycle time is greater than 3.5 hours

Yes, the mean cycle time is greater than 3.5 hours

Step-by-step explanation:

Let us try to calculate the mean cycle time here. Consider the given cycle times. To obtain the mean cycle time, we have.

3.45 + 3.47 + 3.57 + 3.52 + 3.40 + 3.62/6 = 3.505 hours

Hence the difference 3.505 -3.5 = 0.005

Hence mean cycle time is greater than 3.5 by 0.005

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?
