A university conducted a study of online adults that included
419 tablet owners. The study found that 215 tablet owners use their
tablet while watching TV. The authors of the report imply that the
survey proves that more than half of all tablet owners use their
tablet while watching TV at least once per day. Complete parts (a)
through (d) below.

A recent study conducted by a health statistics center found
that 24% of households in a certain country had no landline
service. This raises concerns about the accuracy of certain
surveys, as they depend on random-digit dialing to households via
landlines. Pick three households from this country at random.
Complete parts a) through c) below.
What is the probability that all three, of them have a
landline?
What is the probability that at least one of them does not have...

A recent study conducted by a health statistics center found
that 27% of households in a certain country had no landline
service. This raises concerns about the accuracy of certain
surveys, as they depend on random-digit dialing to households via
landlines. Pick five households from this country at random.
a) What is the probability that all five of them have a
landline?
b) What is the probability that at least one of them does not
have a landline?
c) What...

A study conducted at a major university indicates that the
tendency among undergraduates to seek the assistance of helper
differs by ethnic group. You select 25 subjects each from two
different ethnic groups or business majors and count the number who
sought help. In ethic group A, 11 sought out helpers at some point.
In ethnic group B, 17.
What are the frequency expected values for each group?
Do results support the earlier study?
What does the alternate hypothesis suggest...

A study of the population average income in a certain area was
conducted. A sample of 25 households was selected at random for a
poll. The sample based average annual income was found as (X-bar) =
$53,600, with the sample standard deviation found as (S = $12,000).
Assume that individual records are normally distributed with an
unknown population standard deviation.
Estimate the population average income with the 99% confidence.

The Center for Internet & Society at Harvard
recently conducted a study analyzing the privacy management habits
of teen internet users. In a group of 50 teens, 13 reported having
more than 500 friends on Face-book. Use the “plus four” method to
find a 90% confidence interval for the true proportion of teens who
would report having more than 500 Face-book friends.
What is the size of the sample n:
What is the number of students reported having friends x...

A study done at the Center for Disease at a certain university
tracked 18,169 asymptomatic patients with a certain disease who
started therapy at different points in the progression of the
infection. It was discovered that asymptomatic patients who
postponed antiretroviral treatment until their disease was more
advanced faced a higher risk of dying than those who had initiated
drug treatment earlier.
Consider an experiment designed to determine the effectiveness
of a new drug. The drug is given to participants...
