Question
**Uniform Distribution and Attention Span**

In a study of student attention spans during a 50-minute class, it was found that the attention spans are uniformly distributed according to the following probability density function:

\[ 
f(x) = 
  \begin{cases} 
   c & \text{for } 10 \leq x \leq 50 \\
   0 & \text{otherwise}
  \end{cases} 
\]

**Tasks:**

a) **Determine the Value of \( c \):**
   - What must \( c \) be equal to, for this to be a valid probability density function?

b) **Calculate the Mean and Median:**
   - Determine the mean and median attention span of the students.

c) **Calculate the Standard Deviation:**
   - Determine the standard deviation of the attention span of the students.
