Question

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 who identify as a "dog person."

_______ <p1-p2 < ____________

Answer #1

Here we have to find the confidence interval for difference of proportions of two population.

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...

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.
(Assume that the...

5. In a random sample of 500 people in their 30's, 22% were
smokers. In a random sample of 450 people in their 20's, 14% were
smokers. The 95% confidence interval for the difference between the
population proportions P20's - P30's. turned out to be:
-0.128 < p1 - p2 < -0.032. What does this imply?
There is not a significant difference between the smoking habits
of people in their 20's and people in their 30's, but the sample
showed...

3. In a random sample of 600 families in the city of Ottawa
360 live in a rental housing. Find a 95% confidence interval for
the proportion of the renters in Ottawa.

A study was conducted to determine the proportion of people who
dream in black and white instead of color. Among 299 people over
the age of 55, 61dream in black and white, and among
287 people under the age of 25, 10 dream in black and white. Use
a 0.01 significance level to test the claim that the proportion of
people over 55 who dream in black and white is greater than the
proportion for those under 25. Complete parts...

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)

In a local university, 40% of the students live in the
dormitories. A random sample of 80 students is selected for a
particular study.
What is the sampling distribution of
What is the probability that the sample proportion is
between 0.30 and 0.55(Hint: first draw the normal curve to identify
the area)

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...

A study was done to investigate what people think is "creepy."
Each person in a sample of women and a sample of men were asked to
do the following.
Imagine a close friend of yours whose judgment you trust. Now
imagine that this friend tells you that she or he just met someone
for the first time and tells you that the person was creepy.
The people in the samples were then asked whether they thought
the creepy person was...

A random sample of n1 = 150 people ages 16
to 19 were taken from the island of Oahu, Hawaii, and 14 were found
to be high school dropouts. Another random sample of
n2 = 137people ages 16 to 19 were taken from
Sweetwater County, Wyoming, and 5 were found to be high school
dropouts. Do these data indicate that the population proportion of
high school dropouts on Oahu is different (either way) from that of
Sweetwater County? Use a...
