To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

12 ounces will be left in the bottle
Turn the 1/4 into a decimal which is 0.25 and times that by 20 and you’ll get 5, 5 is the amount of ounces you poured for your friend. Subtract 20 ounces by 5 ounces and you’ll get 15 ounces, then subtract 15 by 3 which is the amount of juice you poured for yourself and you’ll be left with 12 ounces in the bottle.
We are given
v = 18 m/hr west
θ1 = 285°
θ2 = 340°
After 1 hours, the distance traveled by the ship is
dv = 18 mi
The distance between the ship and the lighthouse is
d = 18 / cos 340
Solve for d<span />
Last one:
In the picture a=2, b=4a, b=4•2=8
1st picture a=3, b=4a, b=4•3=12
2nd picture a=0.5, b=4•0.5=2
3rd picture a=2.5, b=4•2.5=10
4th picture a=4, b=4•4=16, but in the picture b=10 therefore, this rectangular is NOT similar to rectangular ABCD.
