Management of Melodic Kortholt Company compared absenteeism rates in two plants on the third Monday in November. Of Plant A's 800 employees, 120 were absent. Of Plant B's 1200 employees, 144 were absent.

C. 1.942

Step-by-step explanation:

This is a test of 2 population proportions. The population proportion of the number of absent employees in plant A and plant B are p1 and p2 respectively.

From the information given,

p1 = 0.15

p2 = 0.12

n1 = 800

n2 = 1200

To determine the z score, we would first determine the pooled proportion.

The pooled proportion, pc is

pc = (x1 + x2)/(n1 + n2)

pc = (120 + 144)/(800 + 1200) = 0.132

1 - pc = 1 - 0.132 = 0.868

The formula for z score is

z = (p1 - p2)/√pc(1 - pc)(1/n1 + 1/n2)

z = (0.15 - 0.12)/√(0.132)(0.868)(1/800 + 1/1200) = - 0.03/0.045

z = 1.942

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
