Question

Which inference can be made from the data in the two-way table?

P(shirt is red|shirt is large) = P(shirt is large)

P(shirt is blue|shirt is large) = P(shirt is blue)

P(shirt is medium and blue) = P(shirt is medium|shirt is blue)

P(shirt is medium and blue) = P(shirt is medium)

P(shirt is large|shirt is red) = P(shirt is red)

Answer 1

Answer the question based on the data in the table.

Shirt
Color Size
Large Medium Total
Red 42 48 90
Blue 35 40 75
Total 77 88 165

Answer 2

A)
P( shirt is red / shirt is large) = 42 /77
P( shirt is large) = 77/ 165
A is false

B)
P(shirt is blue|shirt is large) = 35 / 77
P( shirt is blue) = 75/165
B is false

C)
P( shirt is medium and blue) = 40/165
P( shirt is medium / shirt is blue) = 40 / 75

C is false

D)
P( shirt is medium and blue) = 40/165
P( shirt is medium) = 88/165

E)
P( shirt is large / shirt is red) = 42/90
P( shirt is red) = 90/ 165

The results prove that shirt size and shirt color are not independent.
