Question

A group of friends compared the number of text messages they sent in one week.

Answer 1

Answer:

The sample that best represents the population is the sample of the last eight friends

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

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)
