Question
The student t-distribution approaches the normal distribution as the:Group of answer choicesnumber of degrees of freedom increases.sample size decreases.number of degrees of freedom decreases.the significance level increases.
Solution
The correct answer is: number of degrees of freedom increases.
Explanation:
-
The t-distribution is a type of probability distribution that is symmetric and bell-shaped, like the normal distribution, but has heavier tails.
-
The shape of the t-distribution depends on the degrees of freedom. The degrees of freedom generally equals the sample size minus 1.
-
As the degrees of freedom
