What was a typical length for the male humpback whales that were measured?
Question 4
4.
Do you agree with each of the following statements about the whales that were measured? Explain your reasoning.
More than half of male humpback whales measured were longer than 46 feet.
Question 5
5.
The male humpback whales tended to be longer than female humpback whales.
Question 6
6.
The lengths of the male humpback whales tended to vary more than the lengths of the female humpback whales.
A typical male humpback whale was about 44.5 feet long.
Agree. The lower quartile of the data for the male humpbacks is 43 feet, which means a quarter of the whales are less than 46 feet.
Agree. The lower quartile of the data for the male humpbacks is 51 feet, which means a quarter of the whales are less than 46 feet.
Disagree. The spread is not evenly distributed nor is it symmetrical.
Disagree. The entire distribution for the lengths of female humpbacks is greater than that for male humpbacks, so female humpback whales tend to be longer than their male counterparts.
Disagree. The IQR of the data for female humpbacks is greater than that for male humpbacks, and the range of the data for the females is larger than that for males, so the lengths of the female humpbacks tend to vary more.
Disagree. The minimum value for humpback females lands on the maximum value for the male humpbacks. This shows that the distributions are exactly the same.
