I really need help with answering the last question located towards the very bottom of this text...
In1941,an organization surveyed1100adults andasked, "Are you a total abstainerfrom, or do you on occasionconsume, alcoholicbeverages?" Of the1100adultssurveyed,429indicated that they were total abstainers. In a recentsurvey, the same question was asked of1100adults and407indicated that they were total abstainers.
Complete parts(a) and(b) below.
(a)Determine the sample proportion for each sample.
The proportions of the adults who took the1941survey and therecentsurvey who were total abstainers are0.39and0.37respectively.
(b)Has the proportion of adults who totally abstain from alcoholchanged? Use thea=0.01 level of significance.
First verify the model requirements. Select all that apply.
All of the following answers I selected are highlighter in Bold Black Print and they are already correct.The answer is A,B,and F
A. The sample size is less than5% of the population size for each sample.
B. n1p1(1-p1)>10 and n2p2(1-p2) >10
C.The samples are dependent.
D.The sample size is more than5% of the population size for each sample.
E.The data come from a population that is normally distributed.
F.The samples are independent.
The following question is what I am struggling with. Can you help me figure out what goes in the blank boxes near the very bottom of this question?
H0: p1...BLANK BOX p2 andH1: p1...BLANK BOX p2
Identify the null and alternative hypotheses for this test. Letp1represent the population proportion of1941adults who were total abstainers andp2represent the population proportion ofrecentadults who were total abstainers.
Determine the null and alternative hypotheses.
H0: p1=p2
H1:p1p2
I really need help with this question.....
Find the test statistic for this hypothesis test.
