14. A group of crafters is collecting data on the amount of yarn they use for each scarf knitted. Each person collected 12 piece
s of data and will compile that data to determine a population mean. One crafter, Chris, has a sample mean of 200 meters of yarn. Which statement must be true about this situation?
A. The population mean must be less than 200.
B. The population mean must be greater than 200.
C. The population mean is also 200.
D. There is not enough information to make a conclusion about the population mean.
D. There is not enough information to make a conclusion about the population mean.
Step-by-step explanation:
One of the crafters Chris has a sample means of 200. This means that the average amount of yarn Chris used is 200 meters. Yet there is nothing else given about the other crafters, hence it is impossible to draw a conclusion.
