Question

A piggy bank contains 2 quarters, 3 nickels, and 2 dimes. A person takes 2 coins at random from this bank. Label the coins Q_1, Q_2, N-1, N_2, N_3, D_1, and D_2 so that they can all be regarded as different. Then find the probabilities that the values of the 2 coins selected are the following. The table shows the attendance (In millions) of the top five amusement/theme parks in the United States for have successive years. Attendance at Top Five Amusement/Theme Parks in the United States (In millions) Find the mean (average) and median attendance at Disneyland. Are they greater than the current attendance at Disneyland? Yes, the mean and median are greater than the current attendance. No, the mean and median are not greater than the current attendance.

Explanation / Answer

Mean = n1 + n2 + ..... + n5 / N

N = 5

Mean = 10.3 + 14.1 + 15 + 14.3 + 16 / 5 = 13.94

If N is Even number

Median (nth)= N / 2

If N is odd Number

Median (nth)= (N + 1) / 2

Sort the given value first

10.3, 14.1, 14.3, 15, 16

N = 5 (odd)

5+1 / 2 = 3

3rd sorted Number is 14.3

Median = 14.3

Mean < Media, so the conclusion is

No, the mean and median are not greater than the curent attendance.
