Es necesario saber si los siguentes centiles de la tabla anterior estan correctos?

Determine los siguientes centiles:C25, C50,C75, C80,C90.

Presente el procedimiento.

1. .25 x100= 25

2. CF = 16

3. FC = 57.5

4. 25-16= 22

5. F = 10

C25= 57.5 + (9/10) *5= 62

1. .50 x 100= 50

2. CF = 28

3. FC = 52.5

4. 50-28= 22

5. F= 25

C50= 52.5 + (22/25) *5= 56.90

1. .75x100= 75

2. CF = 71

3. FC = 42.5

4. 75-71= 4

5. F= 10

C75= 42.5 + (4/10) * 5= 44.5

1. .80x100= 80

2. CF = 71

3. FC = 42.5

4. 80-71 = 9

5. F 10

C80= 42.5 + (9/10) * 5= 47

1. .90x100= 90

2. CF = 88

3. FC 32.5

4. 90-88 = 2

5. F = 7

C90= 32.5 + (2/7) * 5= 33.95
