A survey is taken among customers of a fast-food restaurant to determine preference for hamburger or chicken. Of 200 respondents selected, 75 were children and 125 were adults. 120 preferred hamburger and 80 preferred chickens. 55 of the children preferred hamburger and 20 preferred chickens. Set up a 2x2 contingency table using this information and answer the following questions:

What is the probability that a randomly selected individual is an adult?

What is the probability that a randomly selected individual is a child and prefers chicken?

Given the person is a child, what is the probability that this child prefers a

hamburger?

Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?

Are food preference and age statistically independent?

2) Three messenger services deliver to a small town in Oregon. Service A has 60% of all the scheduled deliveries, service B has 30%, and service C has the remaining 10%. Their on-time rates are 80%, 60%, and 40% respectively. Define event O as a service delivers a package on time.

Calculate P(A and O)

Calculate P(B and O)

Calculate P(C and O)

Calculate the probability that a package was delivered on time.

If a package was delivered on time, what is the probability that it was service A?

If a package was delivered 40 minutes late, what is the probability that it was service A?

3) The number of power outages at a nuclear power plant has a Poisson distribution with a mean of 6 outages per year.

What is the probability that there will be exactly 3 power outages in a year?

What is the probability that there will be at least 1 power outage in a year?

What is the variance for this distribution?

What is the mean power outage for this nuclear power plant in a decade?

-In C Programming-

Write a program to display the total rainfall for a year. In addition, display the average monthly rainfall, and the months with the lowest and highest rainfall.

Create an array to hold the rainfall values. Create a 2nd parallel array (as a constant) to hold the abbreviated names of the months. I created my arrays to be 1 element bigger than needed, and then disregarded element [0] (so that my months went from [1] = "Jan" to [12] = "Dec").

Populate the array with the rainfall values entered by the user. Then, display the rainfall values. Display the 1st 6 months, followed by the last 6 months Then display the statistics (the total, average, lowest, and highest rainfall).

Calculate the total rainfall. After you get the total, you should be able to calculate the average (use the size (minus 1 if the array was 1 element bigger than needed) of the array). Then find the index of lowest rainfall and the index of highest rainfall. Finally, display the statistics, using the indexes that were found to get the lowest and highest rainfall value and the name of the month from the arrays.

Format the output to 1 decimal place.

There is no validation.
