Using Statistics to Solve a Problem

Need assistance with this statistic problem - (in excel format)

"Lies, damned lies, and statistics" is a phrase describing the persuasive power of numbers, particularly the use of statistics to bolster weak arguments, and the tendency of people to disparage statistics that do not support their positions. It is also sometimes colloquially used to doubt statistics used to prove an opponent's point.
The term was popularized in the United States by Mark Twain (among others), who attributed it to the 19th-century British Prime Minister Benjamin Disraeli (1804-1881): "There are three kinds of lies: lies, damned lies, and statistics." However, the phrase is not found in any of Disraeli's works and the earliest known appearances were years after his death. Other coiners have therefore been proposed. The most plausible, given current evidence, is Englishman Sir Charles Wentworth Dilke (1843-1911).' (,_damned_lies,_and_statistics)

In total, then, they had 1000 applications from women of which they hired 450, or 45%.
