SUMMARY

The discussion centers on determining the correct value of X in a histogram study where 75% of students sent X or fewer messages out of a maximum of 80 calls. The equation X/80 = 0.75 leads to the conclusion that X should equal 60. However, the textbook states that 75% sent less than 62 messages, clarifying that 62 is not the value of X but rather a threshold. The confusion arises from misinterpretation of the problem statement.

PREREQUISITES

Homework Statement



There was study made, with a histogram shown below where the maximum number of calls made were 80, of the students who sent messages, 75% sent X or less, determine X.

Homework Equations



X/80= 0.75

The Attempt at a Solution



Now unless I'm missing something (which I'll proceed to lash myself if that's true) the answer should be 60, yet the book says 62.

Is this a misprint or am i missing something?

Are you able to upload the histogram you were provided?
 
I should have read the book answer more clearly, i just read it and it says 75% sent LESS than 62 messages, it didn't say 62 was the answer (i.e X)

Sorry folks false alarm, nothing to see here.
