Patients arrive at the emergency room of Costa Val-ley Hospital at an average of 5 per day. The demand for emergency room treatment at Costa Valley fol-lows a Poisson distribution. (a) Using Appendix C, compute the probability of exactly 0, 1, 2, 3, 4, and 5 arrivals per day. (b) What is the sum of these probabilities, and why is the number less than 1?

3. From 2000-2019 there were a total of 3071 earthquakes worldwide with a magnitude of 6 or greater, or an average of about 0.42 such earthquakes per day.* Assume that moving forward the total number of such earthquakes to occur over any time period follows a Poisson distribution with an average of 0.42 earthquakes per day. For the remainder of this question, "earthquake" will mean an earthquake with a magnitude of 6 or greater. Define a new random variable as...

please round to 4 decimal places
The amount of coffee that people drink per day is normally distributed with a mean of 16 ounces and a standard deviation of 5 ounces. 15 randomly selected people are surveyed. Round all answers to 4 decimal places where possible. What is the distribution of X? X N b. What is the distribution of 7 -N c.

The amount of coffee that people drink per day is normally
distributed with a mean of 16 ounces and a standard deviation of 5
ounces. 18 randomly selected people are surveyed. Round all answers
to 4 decimal places where possible.
I don't have a calculator so I have been doing this in Excel. If
I can get the explanation using excel that would be great!
