In Applied Life Data Analysis (Wiley, 1982), Wayne Nelson presents the breakdown time of an insulating fluid between electrodes at 34kV. The times, in minutes, are as follows: 0.22, 0.74, 0.98, 1.36, 2.74, 3.07, 4.02, 4.67, 4.87, 6.42, 7.49, 8.09, 8.26, 12.59, 31.70, 32.63, 33.91, 36.05, and 72.89. Calculate the sample mean and sample deviation of the breakdown data.

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.

step-by-step explanation:

i belive the biggest ratio would be 18: correct me if im wrong

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
