<u>Answer:</u>
The supply of essential goods does not affect demand.
<u>Explanation:</u>
- Essential goods are those without which the subsistence is the most difficult. They support the living at the most basic level by making up all that needs to be necessarily used and consumed in day-to-day life.
- Whether or not the supply for the essential goods is sufficient, the demand for it remains unaffected. That is because the availability of essential goods is a must to lead a decent life.
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.
