Consider the following system:
→ 0.74 → 0.74 →
Determine the probability that the system will operate under each
of these conditions:
a. The system as shown. (Do not round your
intermediate calculations. Round your final answer to 4 decimal
places.)
Probability
b. Each system component has a backup with a probability
of .74 and a switch that is 100% percent reliable. (Do not
round your intermediate calculations. Round your final answer to 4
decimal places.)
Probability
c. Backups with .74 probability and a switch that is 99
percent reliable. (Do not round your intermediate
calculations. Round your final answer to 4 decimal
places.)

In C# The Saffir-Simpson Hurricane Scale classifies hurricanes into five categories numbered 1 through 5. Write an application named Hurricane that outputs a hurricane’s category based on the user’s input of the wind speed. Category 5 hurricanes have sustained winds of at least 157 miles per hour. The minimum sustained wind speeds for categories 4 through 1 are 130, 111, 96, and 74 miles per hour, respectively. Any storm with winds of less than 74 miles per hour is not a hurricane. If a storm falls into one of the hurricane categories, output This is a category # hurricane, with # replaced by the category number. If a storm is not a hurricane, output This is not a hurricane.

Assume that the 129 patients in the Patients dataset (Excel) represent the entire population of interest. If you were interested in age of the patients and took a sample of 25 patients from this population, what is the standard error of the mean? What if you took a sample 64 patients from this population, what is the standard error of the mean? What happens to the standard error of the mean as the sample size increases? Why does that make logical sense?
