Question:
How do u find the results of an unbiased sample of 100 students that are shown on the table. For example the school has a total of 1,150 students prdict how many students would chose cereal(46) pancakes(15) eggs(20) and sandwich(19)

Hi Joseph,

The first thing you should do is change the "counts" 46, 15, 20 and 19 to percents. Since the sample size is 100 this is very easy. Now apply each of the percentages to the population size of 1,150 to get your estimates for the entire population. In a table this might look like:

ChoiceCountPercentPrediction
cereal4646%529   
pancakes1515%172.5
eggs2020%230   
sandwich1919%218.5

The predictions come from taking the appropriate percentage of 1,150.

Cheers
Harley
