For this problem, carry at least four digits after the decimal
in your calculations. Answers may vary slightly due to
rounding.
A random sample of 5,240 permanent dwellings on an
entire reservation showed that 1,634 were traditional
hogans.
(a)Let p be the proportion of all permanent
dwellings on the entire reservation that are traditional hogans.
Find a point estimate for p. (Round your answer to
four decimal places.)
(b)Find a 99% confidence interval for p. (Round
your answers to three decimal places.)
lower limit
upper limit
b2. Give a brief interpretation of the confidence
interval.
a. 1% of the confidence intervals created using this method
would include the true proportion of traditional hogans.
b. 99% of all confidence intervals would include the true
proportion of traditional hogans.
c. 1% of all confidence intervals would include the true
proportion of traditional hogans.
d. 99% of the confidence intervals created using this method
would include the true proportion of traditional hogans.
(c) Do you think that np > 5
and nq > 5 are satisfied for this
problem? Explain why this would be an important consideration.
a. Yes, the conditions are satisfied. This is important because
it allows us to say that p̂ is approximately
binomial.
b. No, the conditions are not satisfied. This is important
because it allows us to say that p̂ is
approximately binomial.
c. Yes, the conditions are satisfied. This is important because
it allows us to say that p̂ is approximately
normal.
d. No, the conditions are not satisfied. This is important
because it allows us to say that p̂ is
approximately normal.
