Standard normal distribution problem: A company found that the daily sales revenue of its flagship product follows a normal distribution with a mean of $5,000 and a standard deviation of $500. The company defines a "high-sales day" as any day with sales exceeding $5,750.       What percentage of days can the company expect to have "high-sales days"?   What is the sales revenue threshold for the bottom 10% of days? (please note that 10% refers to the probability/area under bell curve towards the lower tail of bell curve)   Question 1: What percentage of days can the company expect to have "high-sales days"?
