An airline knows from experience that the number of suitcases lost each week is normally distributed with a mean of 21.4 and a standard deviation of 4.5. Assuming a Poisson distribution, what are the probabilities that in any given week they will lose: a) exactly 25 suitcases? b) at most 25 suitcases? If this is a normal distribution, what are the probabilities that in any given week they will lose: c) exactly 25 suitcases? d) at most 25 suitcases?

1- Determine the number of outcomes in the event. Then decide whether the event is a simple event or not. Explain your reasoning. A computer is used to randomly select a number between 1 and 1000. Event A is selecting a number greater than 600. A.600; Not a simple event because it is an event that consists of more than a single outcome. B.400; Simple event because only one number is selected. C.400; Not a simple event because it is...

What price do farmers get for their watermelon crops? In the third week of July, a random sample of 42 farming regions gave a sample mean of  = $6.88 per 100 pounds of watermelon. Assume that σ is known to be $2.00 per 100 pounds. (a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop (in dollars). What is the margin of error (in dollars)?
