Komok [63]

Answer:

c

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

<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8

<em>Degree of freedom</em> = 2 - 1 = 1

<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415

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

<em>The correct option is </em><em>c</em><em>.</em>

Which of the following samples has the greatest population density?
Andrews [41]

The right answer is D.

The density of a given population is calculated by dividing the number of inhabitants by the area expressed in km² (or in hectares).


Number of inhabitants ÷ area (in km²) = number of inhabitants / km²



A = 125000 organism/ 2.5 m2 = 50,000 organisms / m2


B = 13000 organisms / m2


C = 37500 organisms / m2


D = 200000 organisms / m2
