A researcher reports that the probability of a college student living on campus is p = .38. If a small local college has 2,000 students enrolled, then what is the standard deviation of college students living on campus? Hint: This is a binomial probability distribution.

The standard deviation of the distribution is 21.7 students.

Step-by-step explanation:

We are given the following in the question:

We treat college student living on campus as a success.

P(college student living on campus) = 0.38

Then the number of students follows a binomial distribution.

Sample size, n = 2000

We have to evaluate the standard deviation of the distribution.

Formula:

Putting values, we get,

Thus, the standard deviation of the distribution is 21.7 students.

step-by-step explanation:

a

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
