Put the following in order for the most area in the tails of the distribution. (a) standard normal distribution (b) student's t-distribution with 30 degrees of freedom. (c) student's t-distribution with 50 degrees of freedom. (this is a reading assessment question. be certain of your answer because you only get one attempt on this question.

Highest area) Student's t-Distribution with 30 degrees of freedom

Middle) Student's t-Distribution with 50 degrees of freedom

Lowest are) Standard deviation distribution

Step-by-step explanation:

Knowing that higher area of the tails correspond to higher dispersion of the t- distribution, and the following properties of t-distribution:

- when the degrees of freedom increase , the dispersion diminishes

- when the degrees of freedom goes to ∞ , t- distribution approaches the standard normal distribution ( thus the z-curve is known as t-curve with df=∞ )

the correct answer is

Tail area :  standard deviation < 50 df < 30 df

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
