A USA Today/Gallup poll conducted between 2010 and 2011 asked a
group of unemployed and underemployed Americans if they have had
major problems in their relationships with their spouse or another
close family member as a result of not having a job (if unemployed)
or not having a full-time job (if underemployed). 27% of the 1,145
unemployed respondents and 25% of the 675 underemployed respondents
said they had major problems in relationships as a result of their
employment status.
(a) What are the hypotheses for evaluating if the proportions of
unemployed and underemployed people who had relationship problems
were different?
(b) The p-value for this hypothesis test is approximately 0.35.
Explain what this means in context of the hypothesis test and the
data.
(a)
Ho: punemployed = punderemployed
Ha: punemployed ≠ punderemployed
because, here claim whether proportions of unemployed and underemployed people who had relationship problems were different.
hence, it is a two tailed test.
(b)
Since p ≥ α we do not have enough evidence to reject the null hypothesis
because, rule is
if ( p-Value ) Reject the null hypothesis.
if ( p-Value > ) Failed to reject the null hypothesis.
Here = 0.05 , P-Value = 0.35
here ( p-Value- 0.35 > 0.05)
Hence,
Failed to reject the null hypothesis.
Do not have enough evidence to reject the null hypothesis
