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

Click For 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)

I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
