Were in science class and were using a test kit to measure the amount of calcium in milk. They measured the amount of calcium in 1 cup of milk
10 times and got a mean of 294.6 mg. They looked up the amount of calcium that
is typically in milk and found out it was 290 mg per 1 cup. Percent error finds the
difference between the actual value and measured value and the compares that
difference to the actual value as a percentage. Find the percent error of Mariana
and Felix's measurement.
