Question

Seattle recently passed a tax no sugary drinks. You are interested in the proportion of students who support this tax. You collect a random sample and survey each member by asking "Do you support the sugar-tax?" You record your data as "1" for yes answer, and "0" for any other answer. Below is your sample data:

{1, 0, 1, 0, 1, 0, 0, 0, 1, 1, 0, 1, 0, 0, 1, 0, 1, 1, 1, 0, 1, 0, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 0, 1, 1, 1, 0, 0, 1}

1. What is the population you want to study?

2. Check the 4 condition that required to construct a confidence interval.

3. Construct a 95% confidence interval for the proportion of your population that supports the sugary drink tax.

4. Interpret your interval.

5. Approximately how many students would you have yo survey if you wanted a margin of error of 0.06?

Answer #1

According to medical studies, the world’s intake of sugary
drinks has led to an increase in health issues, including heart
disease and diabetes. This has led to negative externalities for
the world’s population. Countries, including Great Britain and
Finland, are dealing with the externality by establishing a sugar
tax.
In your opinion, do sugar drinks cause negative externalities?
What is a negative externality? Ad do you believe the tax would
correct it?
Your answer must be a minimum of 5...

A soft drink manufacturer wishes to know how many soft drinks
teenagers drink each week. They want to construct a 99% confidence
interval with an error of no more than 0.06. A consultant has
informed them that a previous study found the mean to be 3.7 soft
drinks per week and found the standard deviation to be 1.
What is the minimum sample size required to create the specified
confidence interval? Round your answer up to the next integer.

A soft drink manufacturer wishes to know how many soft drinks
adults drink each week. They want to construct a 95% confidence
interval for the mean and are assuming that the population standard
deviation for the number of soft drinks consumed each week is 1.1.
The study found that for a sample of 949 adults the mean number of
soft drinks consumed per week is 3.6 Construct the desired
confidence interval. Round your answers to one...

A survey is sent to 45
UCF students asking whether or not they understand UCF's
"excess credit hours" policy. Of those, 36 students
answered that they did. Construct the 95% confidence interval for

understand that policy. Answer the following questions related to
that confidence interval, rounding all numeric responses to the
nearest hundredths.
What is the point estimate sample
proportion?
What is the standard
error?

1. Suppose a survey is conducted using a random sample to
determine whether voters in a city are in favour of some project. A
sample with n =100 observations is obtained, and the proportion
found to be in favour of the motion is 40%
i) Construct a 95% confidence interval for the proportion among
the entire population that supports the project.
ii) Construct a 99% confidence interval for the proportion among
the entire population that supports the project.
iii) What...

Suppose you wish to determine the true proportion of the
population that supports marijuana legalization. You poll a
randomly selected sample of 400 individuals and find 61% of them
support legalization.
(a) What is your point estimate for the proportion?
(b) Show that the success/failure conditions hold.
(c) Find the standard error for this estimate.
(d) Compute a 95% confidence interval for this estimate. (e)
Compute a 99% confidence interval for this estimate.

A student was asked to find a 90% confidence interval for the
proportion of students who take notes using data from a random
sample of size n = 78. Which of the following is a correct
interpretation of the interval 0.13 < p < 0.27?
Check all that are correct.
0 There is a 90% chance that the proportion of the population is
between 0.13 and 0.27.
0 The proprtion of all students who take notes is between 0.13
and...
