Explanation:

Step1: Calculate total number of 7th graders

Add the number of 7th graders for each instrument: \(14 + 11+15 + 18=58\)

Step2: Calculate number of 7th graders who play bass

From the table, the number of 7th - graders who play bass is \(11\)

Step3: Calculate the percentage

Use the formula \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\). Here, the part is the number of 7th - graders who play bass (\(11\)), and the whole is the total number of 7th - graders (\(58\)). So, \(\text{Percentage}=\frac{11}{58}\times100=\frac{1100}{58}\approx18.97\)

Answer:

\(19\%\)
