Final answer:
Allison does not need a table to find 80% of 630; she can simply multiply 630 by 0.8, which equals 504. The table options provided are not relevant to this calculation.
Step-by-step explanation:
If Allison wants to find 80% of 630, she does not actually need a table to find this. Instead, she can calculate this by converting the percentage to a decimal and then multiplying by the number. Thus, 80% is the same as 0.8 in decimal form. When you multiply 0.8 by 630, you get 504. Therefore, none of the table options provided (A, B, C, D) is necessary for this calculation.
The information provided from solutions and the examples regarding contingency tables and percentages from data do not relate directly to calculating a percentage of a number, which is what Allison is trying to do. The examples discuss grouping data, finding marginal distributions, and completing tables with given data, which are different concepts related to data analysis, not basic arithmetic operations.
