 P: 9 I have data outlining the number of people who play a musical instrument and data outlining the total number of people in each city play an instrument.............population 255................................1 009 924 179................................3 500 048 556................................ 957 293 etc. how do I write the proportion of people who play an instrument per 100 000 people? Should I do it like this? play an instrument.............population 255................................1 009 924/100 000= 10.09924 179................................3 500 048/100 000=35.00048 556................................ 957 293/100 000=9.57293 255/10.09924=25.25 179/35.00048= 5.11422 556/9.57293=58.01 Thanks :)
 Homework Sci Advisor HW Helper Thanks PF Gold P: 10,255 It's like finding percentages ... only, in this case, you are finding the percentum-milli (?) If n people out of N play an instrument then 100(n/N)% play an instrument, which is 100000(n/N) out of 100000. eg. If there are 50,000 people in the city and 2 of them play an instrument, then 4 out of 100000 play an instrument. It does not matter which order you do the division and multiplications - so what you did works too. You did n/(N/100000) = 100000(n/N) - same thing see? But this way helps you keep it straight in your head what you are doing.
 P: 85 Depending on the country, I suppose. In Africa, maybe as high as 10%.

Just look at the DATA given.In exams,you are not asked to find the true amount of people playing instruments.You only have to consider what's given in the DATA
