Answer
For 12, percentile=$7th$
For 28, percentile=$21st$
For 35, percentile=$36th$
For 42, percentile=$50th$
For 47, percentile=$64th$
For 49, percentile=$79th$
For 50, percentile=$93rd$
47
Work Step by Step
Find the percentile rank of each value.
n=7, use the formula for percentile rank, we have
For 12, percentile=$\frac{0+0.5}{7}\times100\approx7th$
For 28, percentile=$\frac{1+0.5}{7}\times100\approx21st$
For 35, percentile=$\frac{2+0.5}{7}\times100\approx36th$
For 42, percentile=$\frac{3+0.5}{7}\times100=50th$
For 47, percentile=$\frac{4+0.5}{7}\times100\approx64th$
For 49, percentile=$\frac{5+0.5}{7}\times100\approx79th$
For 50, percentile=$\frac{6+0.5}{7}\times100\approx93rd$
What value corresponds to the 60th percentile?
$c=\frac{60\times7}{100}\approx5$
Identify the 5th value as: 47
