Answer:

X² =4.75

Step-by-step explanation:

The formula for calculating the chi square value is expressed as

X² = [ (O - E)²/ E ].

O is the observed frequency

E is the expected frequency

Given

O = 9.5

E = 19

Substitute into the formula:

X² = (9.5-19)²/19

X² = 9.5²/19

X² = 90.25/19

X² = 4.75

Hence the chi square value will be 4.75
