Question
With more degrees of freedom a t-distribution becomes:Question 6Answera.More flat, with thicker tailsb.More left skewed, with a longer left tailc.More right skewed, with a longer right taild.More pointy, with thinner tails
Solution
The t-distribution becomes more pointy, with thinner tails as the degrees of freedom increase. So, the correct answer is d. More pointy, with thinner tails.
Here's why: The t-distribution is a type of probability distribution that is symmetric and bell-shaped, like the standard normal distribution, but has heavier tails, meaning it has more values at the extremes. The shape of the t-distribution changes based on the degrees of freedom. The degrees of freedom refers to the number of independent observations in a set of data. When the degrees of freedom increase, the t-distribution becomes more like a standard normal distribution, which is more pointy or peaked in the middle and has thinner tails.
