Answer:
The quantity of acid in the solution is 47.1 ml
Step-by-step explanation:
Given as :
The quantity of solution of acid and water = 357 millimeters
The percentage of acid in the solution = 13.2 %
Let the quantity of acid in the solution = x ml
<u>So, According to question </u>
13.2 % of the total quantity of acid in the solution = x
I.e x = 13.2 % × 357
Or, x = × 357
Or, x = 0.132 × 357
∴ x = 47.124 millimeters
So , The quantity of acid = 47.1 ml
Hence The quantity of acid in the solution is 47.124 ml Answer
Answer:
Our population of interest represent all the adults in United states who never travel using commercial airlines.
The sample on this case represent the people surveyed in United States who never travel using commercial airlines.
For this case the value obtained represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by
Step-by-step explanation:
A statistic is a "characteristic of a sample". And the statistic allows "estimate the value of a population parameter".
A parameter is a value who represent the population of interest.
For this case we have a sample size of size n = 2276
The proportion estimated of people that nevel travel using commercial airlines was:
or 33%
Our population of interest represent all the adults in United states who never travel using commercial airlines.
The sample on this case represent the people surveyed in United States who never travel using commercial airlines.
For this case the value obtained represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by
