Final answer:
The provided information does not contain specific data about the number of female students with grades lower than 55. We need this data to calculate the sought percentage.
Step-by-step explanation:
To determine the percentage of females who received grades lower than 55, you would need specific data showing the number of female students and how many of those scored below 55. Unfortunately, the provided information does not contain these details. Normally, if you had the number of female students scoring below 55 and the total number of female students, you could calculate the percentage using the formula:
Percentage = (Number of females with grades < 55 / Total number of females) × 100
Since we lack the required data, further information is necessary to answer your question accurately.
