Question

which pieces of information can be gathered from these histograms? choose all answers that apply: a movies based on marble heroes bring in more money on average. b all marble movies bring in more money than all dx movies. c the amount earned by dx movies varies much more than the amount earned by marble movies. d none of the above

Explanation:

• Option A: Histograms can show the central tendency (like average) of data. If the distribution of Marble - hero - based movies' earnings has a higher central value (e.g., mean) than DX movies, we can say they bring in more money on average. This is a valid inference from histograms.
• Option B: Saying "all" Marble movies bring in more money than "all" DX movies is incorrect. Histograms show distributions, and there can be overlap (some DX movies may earn more than some Marble movies), so we can't conclude "all" from histograms.
• Option C: The spread (variation) of data in histograms can be observed. If the DX movies' earnings histogram is more spread out (wider range, more variance) than Marble movies', we can say the amount earned by DX movies varies more. But from the options, we first analyze option A. Since option A is a valid inference (about average from histogram's central tendency) and option B is incorrect, and we assume the histogram shows that Marble - hero - based movies have a higher average.

Answer:

A. Movies based on Marble heroes bring in more money on average.
