Question
Transcribed Image Text:avieue vear 56% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 700 females aged 15 and older and finds that 400 are living alone
sufficient evidence at the a = 0.1 level of significance to conclude the proportion has changed?
Because npo (1- Po)
10, the sample size is
5% of the population size, and the sample
the requirements for testing the hypothesis
%D
satisfied.
(Round to one decimal place as needed.)
Identify the null and alternative hypotheses for this test.
versus H:
(Type integers or decimals. Do not round.)
Find the test statistic for this hypothesis test.
Zo = (Round to two decimal places as needed.)
Determine the P-value for this hypothesis test.
P-value =
(Round to three decimal places as needed.)
tate the conclusion for this hypothesis test.
OA. Reject Ho- There is not sufficient evidence at the a = 0.1 level of significance to conclude that the proportion of females who are living alone has changed.
B. Do not reject Ho. There is not sufficient evidence at the a = 0.1 level of significance to conclude that the proportion of females who are living alone has changed.
C. Reject Ho- There is sufficient evidence at the a = 0.1 level of significance to conclude that the proportion of females who are living alone has changed.
D. Do not reject Ho. There is sufficient evidence at the a= 0.1 level of significance to conclude that the proportion of females who are living alone has changed.
