. Determine the 95th percentiles of IQ scores? (Round to 1 decimal places) The 95th percentile is 3. Suppose that your IQ score is 100. Compute the proportion of people who would receive an IQ score higher than yours (Round to 4 decimal places) The proportion is 4. Compute the lowest score a person should have to be among the top 15% of all IQ scores (Round to 1 decimal places) The lowest IQ score to be among the top 15% is
