Final answer:
Without specific data regarding how many students received and clicked on Layla's emails, it is impossible to determine the percentage of students who engaged with the link. Thus, we cannot confidently answer the question as it seems to be missing necessary information.
Step-by-step explanation:
To determine the percentage of students who clicked on the link from Layla's emails, we would need additional information regarding the total number of students who received Layla's emails as well as the number of those students who actually clicked on the link. Without this information, we cannot accurately calculate the required percentage. Therefore, we cannot confidently select one of the options provided (5%, 8%, 12%, 15%) as the correct answer. If a word problem or statistical question in a math exam is asking you to find a percentage, it would typically provide you with the relevant figures or data to perform the calculation. If no data is given, the problem may be missing information or it could be a question testing your understanding of how to approach the problem rather than the calculation itself.
