Final answer:
The absolute value of tcrit decreases as df increases in the t-distribution.
Step-by-step explanation:
The absolute value of tcrit refers to the critical value of the t-distribution. As degrees of freedom (df) increase, the absolute value of tcrit decreases.
This is because as df increases, the t-distribution approaches the standard normal distribution, where the critical values are smaller.
For example, if we compare tcrit values at df = 10 and df = 50, the tcrit value at df = 50 would be smaller than at df = 10.
Therefore, as df increases, the absolute value of tcrit decreases.
