The advantage of employing a random sample is (C) that the population can be generalized from the findings of the observational study.

<h3>What is a random sample?</h3>

In statistics, a simple random sample is a subset of persons taken from a larger set in which a subset of individuals is chosen randomly, all with the same probability.

It is a method of choosing a sample at random.

The outcomes of the observational study can be generalized to the population.

To construct a simple random sample, there are six steps: (a) defining the population; (b) picking your sample size; (c) listing the population; (d) assigning numbers to the units; (e) discovering random numbers, and (f) selecting your sample.

Therefore, the advantage of employing a random sample is (C) that the population can be generalized from the findings of the observational study.

(11,11). The first coordinate in a pair is the x coordinate, which tells you how far to move left of right. The second coordinate is the y coordinate, which tells you how much to move up or down. If you’re translating right, you’re going to add to the first number. If you’re translating left, you would subtract it. If you’re translating up, you add to the second number. If you’re translating down, you subtract from the second coordinate.

You are standing 400ft away from a building that is 850ft tall. Find the angle of elevation from where you’re standing to the to
klio [65]

Answer:

The angle of elevation is approximately 64.8^o

Step-by-step explanation:

Notice that the two pieces of information given: "400 ft away from a building", and building that is "850 ft tall", can be regarded as the two legs of a right angle triangle (see attached image).

Then the angle \theta that we are trying to find (the angle of elevation) can be found by using the arc-tangent function:

tan(\theta)=\frac{850}{400} \\tan(\theta)=\frac{17}{8}\\\theta =arctan(\frac{17}{8})\\\theta = 64.8 ^o

In a class of 25 students, 15 of them have a driver's license. If ten students are randomly selected, what is the expected numbe
const2013 [10]

Answer:

<em>Expected number of students  would have a driver's license = 6</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given data In a class of 25 students, 15 of them have a driver's license

The sample proportion

                                p = \frac{x}{n} = \frac{15}{25} = 0.6

Let 'X' be the binomial distribution

Given sample size 'n' = 10

<em>mean of the binomial distribution or expected number of students  would have a driver's license</em>

                                 μ = n p

                                    = 10 × 0.6

                                   = 6

<u><em>Conclusion</em></u>:-

<em>Expected number of students  would have a driver's license = 6</em>
