A random sample of rivers on the South Island of New Zealand was measured in km The lengths of rivers flowing to the Pacific Ocean had a mean of 131 82 km and a standard deviation of 78 85 km and the lengths of rivers flowing to the Tasman Sea had a mean of 68 44 km and a standard deviation of 68 78 km Which of the following statements best compares the means Select an answer Which of the following statements best compares the standard deviations Select an answer The lengths of rivers flowing to the Pacific Ocean had a higher average than the lengths of rivers flowing to the Tasman Sea The lengths of rivers flowing to the Pacific Ocean had a lower average than the lengths of rivers flowing to the Tasman Sea The middle of the lengths of rivers flowing to the Pacific Ocean was higher than the middle of the lengths of rivers flowing to the Tasman The middle of the lengths of rivers flowing to the Pacific Ocean was lower than the middle of the lengths of rivers flowing to the Tasman The lengths of rivers flowing to the Pacific Ocean were more consistent than the lengths of rivers flowing to the Tasman Sea The lengths of rivers flowing to the Pacific Ocean were less consistent than the lengths of rivers flowing to the Tasman Sea
