(Please do the correct answer, and I will give out brainlest and 20 points.)
Suppose that you wanted to estimate the average amount of time a middle school student spends per day exercising. You decide to do this by taking a random sample of students from your school. You will calculate the mean time spent exercising for your sample. You will then use your sample mean as an estimate of the population mean.
When you are using a sample statistic to estimate a population characteristic, do you want the sampling variability of the sample statistic to be large or small? Explain why.
