Final answer:
The random variables X and Y represent the time to failure of two sensors in an aircraft.
The appropriate distribution for this problem would depend on the characteristics of the time to failure.
A 92 percent confidence interval for the population mean number of unoccupied seats per flight can be constructed using sample data.
The confidence interval represents a range of values estimated to contain the true population mean with a 92 percent confidence level.
Step-by-step explanation:
b. The random variables X and Y represent the time to failure of two sensors in an aircraft.
c. The distribution that should be used for this problem would depend on the characteristics of the time to failure of the sensors. It is not mentioned in the question which distribution is appropriate, so more information would be needed to determine the distribution.
d. A 92 percent confidence interval for the population mean number of unoccupied seats per flight can be constructed using a sample of data. The specific formula for the confidence interval would depend on the distribution of the data.
i. The state of the confidence interval would be a range of values that is estimated to contain the true population mean number of unoccupied seats per flight with a 92 percent confidence level.
