Question

Each sweat shop worker at a computer factory can put together 4 computers per hour on average with a standard deviation of 0.7 computers. 7 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.

- What is the distribution of XX? XX ~ N(,)
- What is the distribution of ¯xx¯? ¯xx¯ ~ N(,)
- What is the distribution of ∑x∑x? ∑x∑x ~ N(,)
- If one randomly selected worker is observed, find the probability that this worker will put together between 3.6 and 3.9 computers per hour.
- For the 7 workers, find the probability that their average number of computers put together per hour is between 3.6 and 3.9.
- Find the probability that a 7 person shift will put together between 26.6 and 27.3 computers per hour.
- For part e) and f), is the assumption of normal necessary? YesNo
- A sticker that says "Great Dedication" will be given to the groups of 7 workers who have the top 15% productivity. What is the least total number of computers produced by a group that receives a sticker? minutes (round to the nearest computer)
