The word that means of lesser rank is _____.
Aleks04 [339]
The word that means of lesser rank is called subordinate. Anyone that is rank lower or below another employee by seniority or position in the office is called a subordinate. In business ethics, a subordinate must respect and obey his/her boss or superior. He/she also takes orders and instructions from the boss in order to carry out a task as asked by the boss. The subordinates are those employees that serve as the hands of the company because they are the ones who worked so hard for the achievement of the company's goals and visions.

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc
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>
