Answer: 4.17%
Step-by-step explanation:
Formula for percentage error = [tex]\dfrac{|\text{Estimated weight - Actual weight}|}{\text{Actual weight}}\times100[/tex]
Given: Estimated weight = 2.5 oz
Actual weight = 2.4 oz
Percentage error = [tex]\dfrac{2.5-2.4}{2.4}\times100\%[/tex]
[tex]=\dfrac{0.1}{2.4}\times100\%\\\\=\dfrac{100}{24}\%=4.17\%[/tex]
Hence, the percent error = 4.17%
