Question
Each sweatshop worker at a computer factory can put together 4.6 computers per hour on average with a standard deviation of 0.9 computers. 16 workers are randomly selected to work the next shift at the factory. Round all answers to 4 decimal places where possible and assume a normal distribution.

**a. What is the distribution of \( X \)?**
\[ X \sim N(4.6, 0.9) \] 

**b. What is the distribution of \( \overline{X} \)?**
\[ \overline{X} \sim N(4.6, 0.225) \]

**c. What is the distribution of \( \sum X \)?**
\[ \sum X \sim N(73.6, ???) \]

**d. If one randomly selected worker is observed, find the probability that this worker will put together between 4.4 and 4.7 computers per hour.**
\[ ??? \]

**e. For the 16 workers, find the probability that their average number of computers put together per hour is between 4.4 and 4.7.**
\[ ??? \]

**f. Find the probability that a 16-person shift will put together between 72 and 75.2 computers per hour.**
\[ ??? \]

**g. For part e) and f), is the assumption of normal necessary?**
\[ \circ \text{Yes} \quad \circ \text{No} \]

**h. A sticker that says "Great Dedication" will be given to the groups of 16 workers who have the top 20% productivity. What is the least total number of computers produced by a group that receives a sticker?**
\[ ??? \text{ computers per hour (round to the nearest computer)} \]
