Please type out answers.
A recent survey showed that in a sample of 100 elementary school teachers, 15 were single. In a sample of 180 high school teachers, 36 were single. Is the proportion of high school teachers who were single greater than the proportion of elementary teachers who were single? Use α = 0.01.a) State the hypotheses that need to be tested (using proper notation)
b) Calculate the pooled estimate of p.
c) Calculate the test statistic.
d) Calculate the P-value OR critical value.
e) Make a conclusion(IN CONTEXT) using the connection between the P-value and alpha level OR test statistic and critical value.

In a recent survey of county high school students, 100 males and
100 females, 66 of the male students and 47 of the female students
sampled admitted that they consumed alcohol on a regular basis.
Find a 90% confidence interval for the difference between the
proportion of male and female students that consume alcohol on a
regular basis. Can you draw any conclusions from the confidence
interval?

In a recent survey of drinking laws, a random sample of
1000 women showed that 65% were in favor of increasing the legal
drinking age. In a random sample of 1000 men , 60% favored
increasing the legal drinking age. Test the hypothesis that the
percentage of women favoring a higher legal drinking age is greater
than the percentage of men. Use a= 0.05

3. In a recent survey of gun control laws, a random sample of
1000 women showed that 65% were in favor of stricter gun control
laws. In a random sample of 1000 men, 60% favored
stricter gun control laws. Test the claim that the
percentage of men and women favoring stricter gun control laws is
the same at α=0.05

According to a recent survey, a random sample of 100 homes sold
in the Baton Rouge metro area had an average sale price of
$263,000. If the population standard deviation of home prices is
$30,000, what is the 90% confidence interval of the true population
average sales price for homes sold in Baton Rouge?
Select one:
(258065, 267935)
(259160, 266840)
(255275, 270725)

A survey at Evashevski University showed that 75% of the student
body believes that the school offers classes at appropriate times
during the school day. To investigate with this feeling is shared
by students specifically within the business department, the
department polled a sample of 100 business students; 64 said they
thought that classes were offered at appropriate times during the
school day.

Many elementary school students in a school district currently
have ear infections. A random sample of children in two different
schools found that 21 of 42 at one school and 15 of 35 at the other
had this infection. Conduct a test to answer if there is sufficient
evidence to conclude that a difference exists between the
proportion of students who have ear infections at one school and
the other. Find the test statistic.
