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.
Accepted Solution
A:
Answer:Highest area) Student's t-Distribution with 30 degrees of freedomMiddle) Student's t-Distribution with 50 degrees of freedomLowest are) Standard deviation distributionStep-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
