Eagle airlines' planes hold only 15 people. Past records indicate that 20% of the people making a reservation do not show up. We will assume that all reservations are independent; that is each reservation is for one person and these reservations are made independent of one another. Suppose that Eagle Air decides to book 18 people for each flight.
1. Determine the Probability that on any given flight, at least on passenger holding a reservation will not have a seat?
2.What is the probability that there will be one or more empty seats for any one flight?
3.Determine the mean and Standard Deviation for this random variable.
Verify that this is valid density function. Find out probability that weight is smaller than 24 ounces.
Perform the 5 steps of hypothesis testing procedure. Please present the calculations and results and Graphs. Make all possible observations and interpret the results
