The Pew Research Center reported in 2018 that 68% of U. S. adults rated
"reducing health care costs" as a national priority. This year a survey is
conducted with a national sample of 1,505 U. S. adults selected by a
combination of landline and cell phone random digit dial. This year's
survey finds that 70% of the sample says that "reducing health care
costs" is a national priority. We test the following hypotheses:
LaTeX: H_0H 0: The proportion of U. S. adults this year who rate
"reducing health care costs" as a national priority is still 0.68.
LaTeX: H_aH a: The proportion of U. S. adults this year who rate
"reducing health care costs" as a national priority is greater than 0.68.
The P-value is 0.045. At a 5% significance level, we would reject the null
hypothesis and concluded that the proportion of U. S. adults this year
who rate "reducing health care costs" as a national priority is greater
than 0.68. Explain the P-value in the context of this issue.
