answer: the best estimate of the mean of the population = 14.
step-by-step explanation:
given: sheri surveyed eighty students, then generated three random samples of twenty-five student responses.
the sample mean= ![\frac{\text{sum of samples}}{\text{number of samples}}](/tex.php?f=\frac{\text{sum of samples}}{\text{number of samples}})
โ the sample mean=![\frac{12+16+13}{3}=\frac{41}{3}=13.666\approx 14](/tex.php?f=\frac{12+16+13}{3}=\frac{41}{3}=13.666\approx 14)
hence, the best estimate of the mean of the population = 14.
