For 228, percentile=$6th$ For 489, percentile=$17th$ For 524, percentile=$28th$ For 597, percentile=$39th$ For 623, percentile=$50th$ For 659, percentile=$61st$ For 736, percentile=$72nd$ For 777, percentile=$83rd$ For 804, percentile=$94th$ 597
Find the percentile rank of each value. n=9, use the formula for percentile rank, we have For 228, percentile=$\frac{0+0.5}{9}\times100\approx6th$ For 489, percentile=$\frac{1+0.5}{9}\times100\approx17th$ For 524, percentile=$\frac{2+0.5}{9}\times100\approx28th$ For 597, percentile=$\frac{3+0.5}{9}\times100\approx39th$ For 623, percentile=$\frac{4+0.5}{9}\times100=50th$ For 659, percentile=$\frac{5+0.5}{9}\times100\approx61st$ For 736, percentile=$\frac{6+0.5}{9}\times100\approx72nd$ For 777, percentile=$\frac{7+0.5}{9}\times100\approx83rd$ For 804, percentile=$\frac{8+0.5}{9}\times100\approx94th$ What value corresponds to the 40th percentile? $c=\frac{40\times9}{100}\approx4$ Identify the 4th value as: 597
