Answer:

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency

Chamber O E Chi-square

A 18 10 $\frac{(18 - 10)^2}{10}$ = 6.4

B 2 10 $\frac{(2 - 10)^2}{10}$ = 6.4

Total Chi-square = 6.4 + 6.4 = 12.8

Degree of freedom = 2 - 1 = 1

Tabulated Chi-square (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

The correct option is c.
