Final answer:
To calculate the area to the right of 2.120 in a t-distribution with 16 degrees of freedom, one would use a statistical calculator or table to find the probability. The exact area cannot be provided without the use of these tools to determine the cumulative probability associated with a t-value of 2.120.
Step-by-step explanation:
To find the area to the right of 2.120 in a t-distribution with 16 degrees of freedom, one would typically use a t-distribution table or a calculator with statistical functions. Since the provided example utilizes invT(0.975, 19) to find a t-value for a 95% two-sided confidence interval, we would do something similar to find our area of interest. The function in the calculator would likely be invT(1 - p, 16), where 'p' is the cumulative probability up to the t-value of 2.120. Unfortunately, without the exact corresponding 'p' value, we can't provide an exact numerical answer here. In practical use, you would input the command into your calculator to get the exact area to the right of the t-value.
