health care public option plan in 2009. 70% of 819 Democrats and 42% of 783 Independents
support the public option.
(a) Calculate a 95% confidence interval for the difference between (pp - P) and interpret it in this
context. We have already checked cond itions for you.
%) (please round to
The confidence interval is:
the nearest percent) Interpret the confidence interval in context:
95% of differences in proportions are contained within this interval
We can be 95% confident that the difference in sample proportions is contained within
our interval
We can be 95% confident that the difference in population proportions is contained
within our interval
(b) True or false (Explain): If we had picked a random Democrat and a random Independent at the
time of this poll, it is more likely that the Democrat would support the public option than the
Independent.
