Complete Question
ymposium 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 498 five-syllable sequences from this manuscript showed that 129 were of the type four short and one long. Do the data indicate that the population proportion of this type of five-syllable sequence is higher than that found in Plato's Symposium? Use = 0.01.
a. What is the value of the sample test statistic? (Round your answer to two decimal places.)
b. Find the P-value of the test statistic. (Round your answer to four decimal places.)
Answer:
a)
b)
Step-by-step explanation:
From the question we are told that:
Probability of Wishart and Leach
Population Size
Sample size
Therefore
Generally the Null and Alternative Hypothesis is mathematically given by
Test Statistics
Therefore P Value is given as
Answer:
Step-by-step explanation:
Let denotes the average braking distance for a population of small car.
Given : It is advertised that the average braking distance for a small car traveling at 65 miles per hour equals 120 feet.
i.e.
Objective of test : Whether the statement made in the advertisement is false
i.e.
Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.
So the null and the alternative hypotheses for the test will be:
