Answer:

Suppose you want to assess student attitudes about the new campus center by surveying 100 students at your school. In this example, the group of 100 students represents the Sample, and all of the students at your school represent the Population.

Step-by-step explanation:

Previous concepts

The term sample represent a set of observations or individuals selected from a population. And we can have a random sample (when all the individuals have the same probability of being selected) or a non random sample (when not all the individuals have probability of inclusion into the sample)

The term population represent the total of observations or individuals with a common characteristic.

If N represent the sample of the population and n the sample size we have always this inequality:

n \leq N

Solution to the problem

Suppose you want to assess student attitudes about the new campus center by surveying 100 students at your school. In this example, the group of 100 students represents the Sample, and all of the students at your school represent the Population.

The chart below shows one store’s sales of computers, listed by model. 2 circle graphs. A circle graph titled May. Poreg, 262; Q
Brrunno [24]

Answer:

b. 98

Step-by-step explanation:

May and June:

May: 223 Dinztop sales

June: 148 Dinztop sales.

So

p = \frac{148}{223} = 0.6637

In June, it sold 0.6637 = 66.37% the amount of computers sold in May.

How many Dinztop computers will be sold in July?

Because of the same percent rate, 0.6637 = 66.37% of the amoutns sold in June.

0.6637*148 = 98

The correct answer is given by option b.
