A sample of 24 observations is taken from a population that has 150 elements. The sampling distribution of is
The first 24-hour location (or rather, the first attempt at converting to a 24-hour schedule) was an Austin, Texas location in 1962, followed by a few others in the following year.
the sum of the upper quartile and lower quartile is 56 and their difference is 24. find upper quartile and lower quartile.

A quartile is 1/4 or 25% of the total. So if you the population is 24 (say in a classroom), then a quartile is 6. Sort the grades lowest to highest, then the bottom 6 are in the lower quartile. The grade for #6 is the lower quartile.

Median is found by the middle number in a sorted data set. So half of the numbers are greater than the median, and half are below the median. Quartile represents one fourth (or 25%) of the data set. They are usually labeled something like first, second, third, fourth (or sometimes top quartile, bottom quartile). For example, if 24 people are in a class and take a test. 24/4 = 6, so the top six grades would be in the top quartile (I don't remember if this is considered first or fourth). If you are in the top quartile, then you did better than at least 75% of the whole class. Since 24 is even, there is no 'middle number', so the arithmetic average of number 12 & 13 are taken to find the median.
