I see the table in the image along with the related questions. Here's a breakdown of the data provided:

The table shows class intervals (`X`), frequency (`f`), cumulative frequency (`cf`), and cumulative percentage (`c%`). The intervals are:

- \( 55-59 \) (Frequency \( f = 1 \), Cumulative Frequency \( cf = 25 \), Cumulative Percentage \( c\% = 100 \))
- \( 50-54 \) (Frequency \( f = 2 \), Cumulative Frequency \( cf = 24 \), Cumulative Percentage \( c\% = 96 \))
- \( 45-49 \) (Frequency \( f = 2 \), Cumulative Frequency \( cf = 22 \), Cumulative Percentage \( c\% = 88 \))
- \( 40-44 \) (Frequency \( f = 2 \), Cumulative Frequency \( cf = 20 \), Cumulative Percentage \( c\% = 80 \))
- \( 35-39 \) (Frequency \( f = 4 \), Cumulative Frequency \( cf = 18 \), Cumulative Percentage \( c\% = 72 \))
- \( 30-34 \) (Frequency \( f = 5 \), Cumulative Frequency \( cf = 14 \), Cumulative Percentage \( c\% = 56 \))
- \( 25-29 \) (Frequency \( f = 2 \), Cumulative Frequency \( cf = 9 \), C

Consider the data in the following table and answer the questions:

a. Find the 50th percentile for this distribution.
b. Find the 60th percentile.
c. What is the percentile rank for X = 42?
d. What is the percentile rank for 44.5?

Learn how to calculate the 50th and 60th percentiles and find percentile ranks for specific values from a frequency distribution table. The problem involves understanding cumulative frequency and applying key percentile formulas.
