Statistics Questionnaire Luis NunezBonn HidalgoPeriod 3

Question 1:Have you ever experience waking up from your sleep and feeling paralyzed? (Waking Sleep Paralysis)

Yes = 33 (37%)No = 56(63%)n=89Ho: BPHS experience of Waking Sleep Paralysis is the same as average at Carlton University, Ottawa, Canada p = .21 (http://www.sciencedirect.com/science/article/pii/S0092656685710173)Ha: p 21%Conditions/Assumptions: Randomness we sampled classrooms randomly (cluster)Independence one persons experience of waking sleep paralysis does not affect anotherLess than 10% - 89 is less than 10% of population of Carlton UniversitySuccess/Failure np = 89(.37) = 32.93 > 10 n(1-p) = 89(.63) = 56.07 > 10We will conduct a 1-Proportion z-Test

With a P-value so low, we reject the Ho. There is evidence that BPHS students experience Waking Sleep Paralysis differently than the population at Carlton University.

Question 2:How many television sets are in your household?

BPHS mean: 3.92Ho: = 2.24Ha: 2.24Conditions/Assumptions:Random we sampled classrooms randomly (cluster) Independence one person does not affect the number of television in anothers householdLess than 10% - 89 is less than 10% of the U.S. populationWe will conduct a t-Test for means

With a P-value so low, we reject the Ho. There is evidence that BPHS students have different numbers of television sets, on average, than the population of the U.S.

Question 3Do you own any type of game console?

Yes = 77 (87%)No = 12(13%)n=85Ho: proportion of BPHS students who own at least 1 game console is the same as national average P = .524 (http://www.gizmag.com/go/7002/)Ha: p .524Conditions/Assumptions: Randomness we sampled classrooms randomly (cluster)Independence one persons ownership of game console does not affect anothers Less than 10% - 85 is less than 10% of U.S. populationSuccess/Failure np = 89(.87) = 77.43 > 10 n(1-p) = 89(.13) = 11.57 > 10We will conduct a 1-Proportion z-Test

With a P-value so low, we reject the Ho. There is evidence that the proportion of BPHS students that own a game console differs from the national average.

Question 4How many text messages do you send per month?

BPHS mean: 3904Ho: = 3339Ha: 3339n = 58http://www.mobileburn.com/news.jsp?Id=11267Conditions/Assumptions:Random we sampled classrooms randomly (cluster) Independence one person does not affect the number of television in anothers householdLess than 10% - 58 is less than 10% of the U.S. populationWe will conduct a t-Test for means

With a P-value so high, we do not reject the Ho. There is no evidence that BPHS students send text messages at a different rate than the general population.

Question 5Is believing that Batman is superior or not to Superman independent of grade level?

Ho: Opinionating that Batman is superior to Superman is independent of grade (10th or 12th grade)Ha: There is an association between believing Batman is superior to Superman and gradeAssumptions/Conditions:Randomness we sampled classrooms randomly (cluster)Less than 10% - there is less than 10% if all humansExpected counts all are greater than 5We will perform a Chi-Squared test df = (2-1)(2-1) = 1

With a P-value so high, we do not reject the Ho. There is evidence that believing that Batman is superior to Superman or not is independent of grade.

Question 6Is believing that a car is a more effective from of transportation than a train or not independent of grade level?

Ho: Opinionating that car is a more effective from of transportation than a train or not is independent of grade (10th or 12th grade)Ha: There is an association between believing a car is a more effective from of transportation than a train or not and grade levelAssumptions/Conditions:Randomness we sampled classrooms randomly (cluster)Less than 10% - there is less than 10% if all humansExpected counts all are greater than 5We will perform a Chi-Squared test df = (2-1)(2-1) = 1

With a P-value so high, we do not reject the Ho. There is evidence that believing that opinionating that car is a more effective from of transportation than a train or not is independent of grade (10th or 12th grade).

Question 7Is experiencing waking sleep paralysis independent of grade level?

Ho: Experiencing waking sleep paralysis is independent of grade (10th or 12th grade)Ha: There is an association between experiencing waking sleep paralysis and grade levelAssumptions/Conditions:Randomness we sampled classrooms randomly (cluster)Less than 10% - there is less than 10% if all humansExpected counts all are greater than 5We will perform a Chi-Squared test df = (2-1)(2-1) = 1

With a P-value so high, we do not reject the Ho. There is evidence that experiencing sleep paralysis is independent of grade level.

Question 8Is witnessing someone in possession or in use of illegal drugs on campus independent of grade?

Ho: Witnessing someone in possession or in use of illegal drugs on campus is independent of grade (10th or 12th grade)Ha: There is an association between witnessing someone in possession or in use of illegal drugs on campus and grade levelAssumptions/Conditions:Randomness we sampled classrooms randomly (cluster)Less than 10% - there is less than 10% if all humansExpected counts all are greater than 5We will perform a Chi-Squared test df = (2-1)(2-1) = 1

With a P-value so high, we do not reject the Ho. There is evidence that believing that opinionating that car is a more effective from of transportation than a train or not is independent of grade (10th or 12th grade).
