Prose rhythm is characterized as the occurrence of five-syllable sequences in long passages of text. This characterization may be used to assess the similarity among passages of text and sometimes the identity of authors. The following information is based on an article by D. Wishart and S. V. Leach appearing in Computer Studies of the Humanities and Verbal Behavior (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 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 to Plato's time (about 427 - 347 B.C.). A random sample of 317 five-syllable sequences from the newly discovered manuscript showed that 61 are of the type two short and three long. Do the data indicate that the population proportion of this type of five syllable sequence is different (either way) from the text of Plato's Republic? Use α = 0.01.
(a)
What is the level of significance?
=_______________
State the null and alternate hypotheses.
H0: p = 0.261; H1: p > 0.261
H0: p = 0.261; H1: p ≠ 0.261
H0: p ≠ 0.261; H1: p = 0.261
H0: p = 0.261; H1: p < 0.261
(b)
What sampling distribution will you use?
The Student's t, since n·p > 5 and n·q > 5.
The standard normal, since n·p < 5 and n·q < 5.
The standard normal, since n·p > 5 and n·q > 5.
The Student's t, since n·p < 5 and n·q < 5.
What is the value of the sample test statistic? (Round your answer
to two decimal places.)
=_____________
(c)
Find the P-value of the test statistic. (Round your answer to four decimal places.)
=_____________
a) The level of significance is 0.01
H0: P = 0.261
H1: P
0.261
b) np = 317 * 0.261 = 82.737
nq = 317 * (1 - 0.261) = 234.263
The standard normal, since np > 5 and nq > 5.
= 61/317 = 0.1924
The test statistic
c) P-value = 2 * P(Z < -2.78)
= 2 * 0.0027
= 0.0054

Symposium is part of a larger work referred to as
Plato's Dialogues. Wishart and Leach† found that about
21.4% of five-syllable sequences in Symposium are of the
type in which four are short and one is long. Suppose an
antiquities store in Athens has a very old manuscript that the
owner claims is part of Plato's Dialogues. A random sample
of 484 five-syllable sequences from this manuscript showed that 128
were of the type four short and one long. Do...
Conduct a hypothesis test for the following scenarios. You may compute the p-value either by simulation or test-statistic 1) 2) 3) at least one problem must be done by test-statistic conversion at least one problem must be done by simulation simulation should involve at least 10,000 trials. The grading scheme is as follows: Identify and describe the parameter of interest. State the null and alternative hypotheses, using correct notation. Be specific with your parameters. 2pts State the value of the...
