To clarify the kind of information conveyed by a level of confidence, Thompson (2007) stated, "CIs are extremely useful because they convey not only our point estimate, but also, via the width of the intervals, something about the precision of our estimates."† What is the name of the estimate that conveys the width of the intervals?

how long did the flood last

step-by-step explanation:

then i will answer

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
