The SAT is a standardized test used by many colleges and universities in their admission decisions. More than one million high school students take the SAT each year. The current version of the SAT includes three parts: reading comprehension, mathematics, and writing. A perfect combined score for all three parts is 2400.

A sample of SAT scores for the combined three-part SAT is as follows:

1665, 1525, 1355, 1645, 1780, 1275, 2135, 1280, 1060, 1585, 1650, 1560, 1150, 1485, 1990, 1590, 1880, 1420, 1755, 1375, 1475, 1680, 1440, 1260, 1730, 1490, 1560, 940, 1390, 1175, 1475, 1680, 1440, 1260, 1730, 1490, 1560, 940, 1430, 1175.

Task: Show a frequency distribution and histogram. Begin with the first class starting at 800 and use a class width of 200.

To create a frequency distribution and histogram for the given SAT scores, group the scores into intervals and create a table and histogram to represent the distribution.

Explanation:

To create a frequency distribution and histogram for the sample of SAT scores, we need to group the scores into intervals called classes. Starting with a class starting at 800 and a class width of 200, we can create the following frequency distribution:

ClassFrequency800 - 99931000 - 1199111200 - 139991400 - 159991600 - 179941800 - 199942000 - 21991

Using this frequency distribution, we can create a histogram to visually represent the distribution of the scores.
