The number of fan letters received by a band each month is distributed normally, with a mean of 6.5 and a standard deviation of 2.5. Use the Z calculator to answer the questions below: 6a) Use continuity correction to determine the probability that the band receives no more than 5 fan letters in a given month. Round to the nearest 0.1%. 6b) Calculate the probability that the average number of fan letters per month which the band receives over a 10-month period at least 7. Round to the nearest 0.1%. MM

7) You have a fruit stand. At the beginning of each week, you order some fruit, and sell it retail at
a 100% markup. For example, a piece of fruit that you sell retail for $5 cost you $2.50. At the end of
the week, any fruit not sold is sold to a juicer for 40% of what you paid for it (or 20% of the retail
price). (For example, you pay $2.50 for a piece of fruit, which you can sell retail for $5, but if you
don't sell it retail you can sell it to a juicer for $1.) a
The average amount of fruit that your customers want to purchase that week is $10,000 (Retail. In
other words, you paid 5,000 for it.). This amount is distributed normally, with a standard deviation
of $1,000.
To maximize your long term profits, how much fruit (in terms of retail price) should you purchase
each week? Round, if necessary, to the nearest $10.
