I believe the answer is Inference.
In creating an inference, you need to find a reliable source to obtain a certain amount of data and information.
After that, you need to process that data/information with your personal knowledge and deductive reasoning in order to create a conclusion
The number of expected males and females to brush their teeth at least twice a day are : 135 males and 147 females.
<h3>What is proportion?</h3>
Proportion refers to the part of the things or numbers which are comparable with each other. For example: the weight of the Rahul is 70kgs and weight of the Mohan is 100kgs. Thus the Mohan's weight is greater than the Rahul's weight.
The pooled samples by combining the sample proportion to that of the successes in the each samples and combining the sample sizes.
P^ = (122+160)/(210+228)= 282/438
Then multiply this pooled sample with the two sample sizes:
Expected males = n1*^p = 210(282/438) = 135.21
expected females =n2*^p = 228(282/438) = 146.79
Thus the expected numbers of males are 135 and expected numbers of females are 147.

<h3 /><h3>What is systems theory?</h3>
It is the understanding that an effective system must be integrated to all its parts, which generates cohesion, learning and greater coverage of the factors that are interconnected to achieve a common objective.
Therefore, systems theory is related to an open system because it is comprehensive, expansive and integrated with a set of parts that together will determine its performance.
