Answer:

4 hours

Step-by-step explanation:

For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:

120 +20x = 50x

120 = 30x . . . . . . . . subtract 20x

4 = x . . . . . . . . . . . . . divide by 30

The electrician worked 4 hours that day.

Before we use an applet to simulate the selection of random samples from this population, let’s make sure we are clear about who

Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

Explanation:-

Introduction:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

Example:-

when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.

If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be small, large but finite or infinite.

Example :- 1

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are finite number of observations.

Example :- 2

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

Population:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the population

The number of observations in the population is defined to be the size of the population.

Example :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

Sample:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population
