The average height of a total of 500 girls in a high school is 63 inches. you randomly sampled 10 girls and measured their weight. you repeated this procedure three times. the means and standard deviations from your 4 samples are listed as following. which sample estimate shows the least sampling variability?

select one:
a. sample one: mean=64, se=5
b. sample two: mean=64, se=2
c. sample three: mean=66, se=3
d. sample four: mean=68, se=5

b) Sample two (mean=64, SE=2) shows the least sampling variability

Step-by-step explanation:

Sampling variability explains the extent to which the measurement obtained from a sample is different from that obtained from the population from which that sample was taken.

Standard deviation shows the deviation of the mean of a sample from the mean of the population.

Sample two, has a mean of 64 which is closest to the population average of 63 inches, and a standard deviation of 2 which is the lowest among the four samples taken. This means sample 2 shows the least sampling variability.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
