A Washginton Post artilcle from 2009 reported that "support for a government-run health-care plan to
compete with private insurers has rebounded from its summertime lows and wins clear majority support from
the public." More specifically, the article says "seven in 10 Democrats back the plan, while almost nine in 10
Republicans oppose it. Indpendents divide 52% against, 42% in favor of the legislation." There were 819
Democrats, 566 Republicans, and 783 Independents surveyed.
(a) A political pundit on TV claims that a majority of Indpendents oppose the health care public option plan.
Do these data provide strong evidence to support this statement at the 5% level of significance?
The hypotheses for this test are:
Но: р 3D .5
На: р <.5
О Но: р %3D .5
На: р > .5
Ho: p = .5
Ha: p z .5
The test statistic is: Z=
(please round to two decimal places) The p-value associated
with this hypothesis test is:
(please round to four decimal places) What is the
conclusion of the hypothesis test?
Since p 2 a we accept the null hypothesis
Since p 2 a we fail to reject the null hypothesis
Since p 2 a we reject the null hypothesis and accept the alternative
Since p<a we reject the null hypothesis and accept the alternative
Since p<a we fail to reject the null hypothesis
Interpret the result of the test in the context of this study and article:
The data do not provide sufficient evidence at the 5% level of significance to claim that that a majority
of Independents oppose the public option.
The data provide sufficient evidence at the 5% level of significance to claim that a majority of
Independents oppose the public option.
(b) Would you expect a confidence interval for the proportion of Independents who oppose the public option
to include 0.5?
no

Expert Solution

Step 1

Only Z value and P-value are asked in the Question :

The following information is provided:

The sample size is $N = 783$ , the number of favorable cases is $X = 407.16 \approx 407$ , and the sample proportion is $\overset{ˉ}{p} = \frac{X}{N} = \frac{407}{783} = 0.5198 \approx 52 %$ , and the significance level is $\alpha = 0.05$
