An economist was curious if the mean yearly amount of seafood consumed in Sweden is significantly different than the mean yearly consumption in the United States. They randomly selected 125 citizens in Sweden and determined their sample mean is 12 kg with a standard deviation of 5.2 kg. The 140 randomly selected U.S. citizens had a sample mean of 9.7 kg with a standard deviation of 5.8 kg. Is this sufficient evidence to say that the mean consumption is different?

Sweden is significantly different than the mean yearly consumption in the United
States. They randomly selected 125 citizens in Sweden and determined their
sample mean is 12 kg with a standard deviation of 5.2 kg. The 140 randomly
selected U.S. citizens had a sample mean of 9.7 kg with a standard deviation of 5.8
kg. Is this sufficient evidence to say that the mean consumption is different?
Which are the correct hypothesis statements for this situation?
