Consider a document that has 1000 words in total and the word "data" occurs 100 times in the document. Also, assume that the corpus size is 10 million documents and the word "data" appears in 1000 of those documents. Calculate the TF-IDF weight.

How Many English Words? A simple random sample of 10 pages from Merriam-Webster's Collegiate Dictionary is obtained. The numbers of words defined on those pages are found, with these results: $n=10, \bar{x}=53.3$ words, $s=15.7$ words. Given that this dictionary has 1459 pages with defined words, the claim that there are more than 70,000 defined words is equivalent to the claim that the mean number of words per page is greater than $48.0$ words. Assume a normally distributed population. Use a $0.01$ significance level to test the claim that the mean number of words per page is greater than $48.0$ words. What does the result suggest about the claim that there are more than 70,000 defined words?
