Question

A random sample of n 1 = 273 people who live in a city were selected and 105 identified as a "dog person." A random sample of n 2 = 99 people who live in a rural area were selected and 52 identified as a "dog person." Find the 90% confidence interval for the difference in the proportion of people that live in a city who identify as a "dog person" and the proportion of people that live in a rural area who identify as a "dog person." Round answers to to 4 decimal places.

< p 1 − p 2 <

Answer #1

A random sample of n1n1 = 219 people who live in a city were
selected and 88 identified as a "dog person." A random sample of
n2n2 = 110 people who live in a rural area were selected and 66
identified as a "dog person." Find the 95% confidence interval for
the difference in the proportion of people that live in a city who
identify as a "dog person" and the proportion of people that live
in a rural area...

A random sample of 1300 voters in a particular city found 273
voters who voted yes on proposition 200. Find a 95% confidence
interval for the true percent of voters in this city who voted yes

of a percent.

Market researchers selected a random sample of people from
region A and a random sample of people from region B. The
researchers asked the people in the samples whether they had tried
a new product. The difference between the sample proportions (B
minus A) of people in the regions who indicated they had tried the
new product was 0.15. Under the assumption that all conditions for
inference were met, a hypothesis test was conducted with the
alternative hypothesis being that...

between 0.30 and 0.55(Hint: first draw the normal curve to identify
the area)

Gamers" are described as people who regularly play video games.
A random sample of 80 people was selected and 50 were found to be
male. The 95% confidence interval for the proportion based on this
sample is ________. A. (0.519, 0.731) B. (0.571, 0.679) C (0.463,
0.787) D. (0.536, 0.714)

A random sample of construction workers was taken in a large
city. Of the 125 workers sampled, 21 were unemployed. We wish to
construct a 99% confidence interval for the proportion of
unemployed construction workers in this city. Assume all
assumptions and conditions are met.
Part 1 - find the sample proportion
part 2 What critical value would you use to be 99% confident?
Part 3 Use the appropriate formula to build the confidence
interval.
Part 4 If we wanted...

1. In a random sample of 58 people aged 20-24, 22.7% were
smokers. In a random sample of 110 people aged 25-29, 29.5% were
smokers. Calculate the margin of error for a 95% confidence
interval that can be used to estimate the difference between the
population proportions p1 − p2 of the smokers
in these age groups.
Show your answer in decimal form, rounded to three
decimal places.
2. Confidence interval for the difference between
population proportions.

Consider a survey of customers who bought a Christmas tree
during the holiday season. Respondents were classified as either
living in a rural area (population #1) or living in an urban area
(population #2). Each respondent was asked whether they purchased a
natural tree or an artificial tree. The population proportions in
this study are the proportion of persons who bought a natural tree
(“success”). (Assume, for this analysis, that the survey was
conducted by drawing an SRS from rural...
