MHB Solve Statistics Exercise: 1500 in Biology vs Physics Pie Chart

AI Thread Summary
The discussion revolves around solving a statistics exercise involving a pie chart that represents student distribution in a faculty of science with 3000 students. The user knows that 1500 students are in biology but is unsure how to determine the number of students in physics based on the pie chart. Participants suggest that without a scale or measuring device, any estimate would be imprecise. One response humorously indicates that the difference could be described as "a lot," highlighting the lack of specific data. Ultimately, the conversation emphasizes the challenge of making accurate calculations without clear visual aids.

Hello, I'm not familiar with basic statistics exercises using pie chart and I'd like to know how i can solve this one: in a faculty science of 3000 students, some are in biology, some in physics and some in chemistry as shown on the pie chart. I can for sure tell that 1500 students are in biology. The question asked is how many more students are there in biology compared to physics? I don't know how to tackle this.

Thanks for your help in advance!

Best you can do with the pie chart given is an estimate.

See what you can do to improve that estimate if a measuring device is used ...
 
There's no device used so I thought some statistical calculations were involved... Thanks for the quick response!

Since they didn't give you an actual scale to say with any precision, my answer would be "a lot." (Angel)

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
