a) We wish to estimate what percent of adult residents in a
certain county are parents. Out of 200 adult residents sampled, 152
had kids. Based on this, construct a 95% confidence interval for
the proportion ?? of adult residents who are parents in this
county.
Give your answers as decimals, to three places.
_____ < ? < _____
b) Out of 200 people sampled, 150 preferred Candidate A. Based
on this, estimate what proportion of the voting population (??)
prefers Candidate A.
Use a 99% confidence level, and give your answers as decimals, to
three places.
_____ < ? < _____
c) Assume that a sample is used to estimate a population
proportion p. Find the margin of error M.E. that
corresponds to a sample of size 238 with 181 successes at a
confidence level of 90%.
M.E. = _____%
(report answer accurate to one decimal place; answer should be
reported as a percent, not a decimal—though do not type the percent
sign)
Answer should be obtained without any preliminary rounding.
However, the critical value may be rounded to 3 decimal places.
