Click For Summary

Homework Help Overview

The discussion revolves around a homework problem related to frequency distribution, specifically focusing on part II of the assignment. Participants are seeking guidance on how to approach the calculations required in this part, referencing previous work submitted for part I.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Some participants express confusion regarding the wording of the problem, particularly the use of "calculate" versus "estimate." Others suggest that a graphical approach might be useful for estimation.

Discussion Status

The discussion is ongoing, with participants questioning the clarity of the problem statement and the feasibility of calculating certain values based on the provided information. There is a recognition that the current data may not allow for precise calculations, leading to suggestions for estimation methods instead.

Contextual Notes

Participants note that the problem lacks specific information about the distribution of values within certain ranges, which complicates the ability to calculate percentages or other metrics accurately.

See the document "Guidelines for Students and Helpers", at the start of this Forum; in particular, pay attention to topic 5 (about how and why should not just post images).
 
Since it says "calculate", I would say there is a mistake in the question.
If it had said "estimate" then I would suggest drawing graph and fitting a smoothish curve to it.

I would be willing to help if you typed it out, but I do not look at attached photos of handwritten work. As I said, read the posting "Guidelines for students and helpers", topic 5.

Was I not clear? There is no way to calculate it from the given information. You could estimate it, by the method I described.
 
The point is that you are told how many people there are between 30 and 49 but have NO way of knowing how many people are between 30 and 35. If the problem asked for the percent between 19 and 30 or between 19 and 49 then you could answer. But the way the problem is given, you cannot know how many people there are between 19 and 35 and so cannot know what the percentage is
