True or False: Point estimation is a form of statistical inference in which, based on the sample data, we estimate the unknown p
storchak [24]

Answer:

True

Step-by-step explanation:

Point estimation of a population parameter provides an estimate of  a single value calculated from the sample that is likely to be close to its value to the unknown parameter. Itis to be noted that a point estimate will not in general be equal to the population parameter as the random sample used is one of the many possible samples which could be chosen from the population.

For example, in estimation, we may estimate the mean and the variance of a population by computing the mean and the variance of the sample drawn from a population.

[-9,-4] U (-4, 19)<br><br><br> Simplify the following Union and/or intersection
Kay [80]

The union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.

<h3>What is a set?</h3>

A set is simply a  mathematical model for a collection of different things which could be elements or members.

Union of sets represented with '∪' is the combination of two sets without repetition

Intersection of sets represented with '∩' is the sum of elements common between the.

From the expression given, we have;

[-9,-4] U (-4, 19)

= { -4, -9 , 19}

[-9,-4] U (-4, 19)

= { -4}

Thus, the union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.
