Question
Transcribed Image Text:A flight attendant selects a random sample of 201 travelers. For each, he records the class in which the person
travels and whether they have carry-on luggage. He would like to know if there is convincing evidence that the class
in which a person travels is associated with having carry-on luggage. Let a = 0.05.
What are the hypotheses for this test?
O Ho: Class is not independent of carry-on luggage.
Hg: Class is independent of carry-on luggage.
O Họ: Class is independent of carry-on luggage.
Hg: Class is not independent of carry-on luggage.
O Họ: There is an association between class and carry-on luggage.
Hạ: There is no association between class and carry-on luggage.
O Ho: The proportion of travelers who have carry-on luggage is not the same in the types of class.
Hg: The proportion of travelers who have carry-on luggage is the same in the types of class.

An AP Statistics student decided to conduct her own survey at her high school of 3,260 students. She randomly selected 239 students to be surveyed and 99 of them stated that they had been harassed online. Does her survey suggest that the problem is worse at her school than it is for a typical person in the region? Determine the appropriate hypotheses. Ho P HA P (Type integers or decimals.) The test statistic is z = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State your conclusion. Use a = 0.05. the null hypothesis.

In League B, the pitcher must bat. The common belief is that this results in League A teams scoring more runs. In interleague play, when League A teams visit League B teams, the League A pitcher must bat. So, if the DH does result in more runs, it would be expected that league A teams will score more runs in League A park than when visiting League B parks. To test this claim, a random sample of runs scored by league A teams with and without their DH is given in the accompanying table. Complete parts a) through d) below.

A researcher wanting to test this claim randomly sampled 84 such people. She filled 84 plain white cups with soda, half diet and half regular through random assignment, and asked each person to take one sip from their cup and identify the soda as diet or regular. 51 participants correctly identified the soda. Conduct and interpret a hypothesis test for the following question: are these people any better or worse at telling the difference between diet and regular soda than random guessing (correctly identify soda half of the time)? HINT: what is your hypothesized proportion if you want to test if these participants are right or not half of the time? Use a = .01 significance level.
