Question
**Problem: Distribution and Probability**

The number of seconds \( X \) after the minute that class ends is uniformly distributed between 0 and 60. Round all answers to 4 decimal places where possible.

a. What is the distribution of \( X \)?  
\[ X \sim U(0, 60) \]

Then the sampling distribution is 

b. Suppose that 37 classes are clocked. What is the distribution of \( \bar{x} \) for this group of classes?  
\[ \bar{x} \sim N \left( \frac{60}{2}, \frac{60}{\sqrt{12 \times 37}} \right) \]

c. What is the probability that the average of 37 classes will end with the second hand between 23 and 27 seconds?  
\[ \text{Probability} = P(23 < \bar{x} < 27) \]
