Question 408052: The number of baby deliveries in a small hospital was sampled over 12 hour periods. Below is the sample:
18 21 9 16 8 4 21 16 9 5
12 16 5 9 7 25 14 9 17
From this data set, compute the sample mean, median, mode and midrange. Compute the 1st
quartile and 3rd and interpret their meanings.

You can put this solution on YOUR website! 4 5 5 7 8 9 9 9 9 12 14 16 16 16 17 18 21 21 25
Mean is 241/19 = 12.68421, to 5 decimal places.
Median is the 10th entry, 12
Mode is 9.
Midrange is (4 + 25)/2 = 14.5
The 1st quartile is between the 4th and 5th terms: (7+8)/2 = 15/2 = 7.5.
The 3rd quartile is between the 14th and 15th terms: (16+17)/2 = 16.5.
The 1st quartile 7.5 separates the lowest 25% of the distribution from the rest.
The 3rd quartile 16.5 separates the highest 25% of the distribution from the rest.
