To estimate the enrollment rate in 2003, we need to look at the trend in enrollment rates from 1995 to 2000. We can see that there is a steady increase of 1.2% each year. If we continue this trend, we can estimate that the enrollment rate in 2003 would be 65.3%. This is calculated by adding 3 years of increase (1.2% x 3 = 3.6%) to the 2000 enrollment rate of 61.7%. Therefore, our estimate for the enrollment rate in 2003 is 65.3%.
