The responses were as follows: M B B M F S B M F M B F B M M B B F B M a. Determine the frequency for patients who live with both parents( ), mother only( ), father only( ) , or someone else( ) . b. Determine the relative frequency (compute to two decimal places) for patients who live with both parents( ), mother only( ), father only( ), or someone else( ). c. Determine the frequency percentage for patients who live with both parents( )%, mother only( )%, father only( )%, or someone else( )%. d. Would you expect a score of 85 to fall above or below the 85th percentile? ( ) Would you expect a score of 70 to fall above or below the 60th percentile? ( )   e. What is the average of all scores? ( )

Answer 1

a. The frequency for patients who live with

Both parents - 8

Mother only - 7

Father only - 4

Someone else - 1

b. The relative frequency for patients who live with

Both parents = 8 $\div$ 20 = 0.4

Mother only = 7 $\div$ 20 = 0.35

Father only = 4 $\div$ 20 = 0.2

Someone else = 1 $\div$ 20 = 0.05

c. Frequency percentage for patients who live with

Both parents = 0.4 $\times$ 100 = 40%

Mother only = 0.35 $\times$ 100 = 35%

Father only = 0.2 $\times$ 100 = 20%

Someone else = 0.05 $\times$ 100 = 5%
