Standard error for a sample proportion, p = 0.8, n = 1200
Answer:
its very long but ill help you with the first answer:18.5753424657534247
Step-by-step explanation:
Since it's a local (a possible branch) hardware store, it's POSSIBLE BUT VERY UNLIKELY:
PROOF: Assume 100 clients/day are buying from this store, that means,
3,600 customer a month or 43,200 clients a year. The one-millionth customer will occur after 1,000,000/43,200 = 23 years. or it will be after 46 years if the average customer is 50/day. So it is possible but MOST UNLIKELY
The answer is y=2/5x+7.
Hope that helps! :D
