Answer: Sample statistics are used to make inferences about population parameters.
Step-by-step explanation:
A number which describes a population is called a parameter, such as a proportion or percentage.
A statistic is a number which may be calculated from the data observed in a random sample without demanding the use of any unknown parameters.
The mean and variance of a population are population parameters.
Thus, fourth statement is the right answer "Sample statistics are used to make inferences about population parameters."

Answer:
10
Step-by-step explanation:
When i divide into ratio, i like to think of them as units:
so 24 will be divided into units, where the first thing gets 3 units and the second 5 units. In total those are 3+5=8 units.
so each unit will have 24/8=4
so the division into the two numbers is like this: the first one gets 3 units (3*4=12) and the second 5 (5*4=20)
so it's 12:20.
