Let's analyze the given data to fill in the statements.
1. The percent of labor force in the mining sector in 1887 was 14% and in 1930 it was 26%. Therefore, the change in the mining sector is:
[tex]\[
\text{Change in mining percentage} = 26\% - 14\% = 12\%
\][/tex]
2. The percent of labor force in the manufacturing sector in 1887 was 20% and in 1930 it was 38%. Therefore, the change in the manufacturing sector is:
[tex]\[
\text{Change in manufacturing percentage} = 38\% - 20\% = 18\%
\][/tex]
Given these calculations, it's evident that:
- The percentage of labor force in both the mining and manufacturing sectors increased between 1887 and 1930.
- The manufacturing sector had the highest increase with an 18% rise.
So, the completed statements should be:
1. The percent of labor force in the mining and manufacturing sectors increased between 1887 and 1930.
2. The manufacturing sector increased the most.
3. This increase is most likely because of industrialization.
