Answer:
<u>The sample that best represents the population is the sample of the last eight friends </u>
Step-by-step explanation:
Let's find out the sample that best represents the population, this way:
Mean of the number of text messages a group of 24 friends sent in one week = 10,700/24 = 445.83
Mean of the sample of the first six friends = 1,850/6 = 308.33
Mean of the sample of the first ten friends = 3,300/10 = 330
Mean of the sample of the last twelve friends = 6,500/12 = 541.67
Mean of the sample of the last eight friends = 4,150/8 = 518.75
<u>The sample that best represents the population is the sample of the last eight friends, because its mean is the closest to the population mean (445.83 and 518.75)</u>
