webassign.net MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 50 records of automobile driver fatalities in a certain county showed that 33 Prose rhythm is characterized as the occurrence of five-syllable sequences in long passages of text. This characterization may be used involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than to assess the similarity among passages of text and sometimes the identity of authors, The following information is based on an article 77% in Kit Carson County? Use cr - 0.05. by D. Wishart and S. V. Leach appearing in Computer Studies of the Humanities and Verbal Behawor (Vol. 3, pp. 90-99). Syllables were categorized as long or short. On analyzing Plato's Republic, Wishart and Leach found that about 26 1% of the hat about 26.1% of the five-syllable sequences are of the type in which two are short and three are long, Suppose that Greek archaeologists have found an ancient manuscript dating back LA USE SALT to Plato's time (about 427 - 347 B.C.). A random sample of 313 five-syllable sequences from the newly discovered manuscript showed that 60 are of the type two short and three long. Do the data indicate that the population proportion of this type of five syllable sequence (2) What is the level of significance? is different (either way) from the text of Plato's Republic?
