### Statistical Analysis of Video Game Content

**Context:**
A study was conducted on sixteen different video games to observe the duration of drug use scenes. The duration times (measured in seconds) were recorded for analysis.

**Analysis Objective:**
The goal is to perform a t-test to assess the claim that the population mean duration of drug use scenes is greater than 87 seconds. This involves identifying and calculating the necessary statistical parameters.

**Key Question:**
What does the symbol \( t \) denote, and what is its value?

**Options:**
- **A.** The sample size
- **B.** The sample standard deviation
- **C.** The number of degrees of freedom
- **D.** The test statistic

**Additional Task:**
Calculate the value of \( t \).
*(Note: Enter this as an integer or decimal, without rounding.)*
