Question

A random sample of 100 students at a high school was asked
whether they would ask their father or mother for

help with a financial problem. A second sample of 100 different
students was asked the same question

regarding a dating problem. If 43 students in the first sample and
47 students in the second sample replied that

they turned to their mother rather than their father for help, test
the hypothesis of no difference in the

proportions. Use α = 0.02.

Use any method, however, follow the PHANTOMS acronym.

**P - Parameter Statement**

**H - Hypotheses**

**A - Assumptions & Conditions**

**N - Name the Test and state the curve you're
using**

**T - Test Statistic - Round your value to TWO decimals
and state the command you used to find this value**

**O - Obtain the P-Value or Critical Value . State the
command you are using to find these values**

**M - Make a Decision about the Null Hypothesis and
explain why**

**S - State Your Conclusion About the Claim**

A random sample of 100 students at a high school was asked
whether they would ask their parent(s) for help with a financial
problem, in which 47 of them replied yes. A second sample of 100
different students was asked the same question regarding a dating
problem, in which 43 of them replied yes. Construct a 98%
confidence interval for p1-p2, the difference in the
population proportions of high school students that would ask their
parents for financial help versus...

A random sample of 100 traditional aged college students were
asked whether they
would turn to their father or mother for advise if they had a
personal problem. A second
sample of 100 different traditional aged college students was asked

Q1) A random sample of 10 travel brochures showed sample mean
cost of an 8-day cruise to the Bahamas $1,978. (1st class, double
occupancy). The sample standard deviation was $250. An independent
random sample of 12 travel brochures showed mean cost of a
comparable 8 day cruise to Mexico $2,150 with sample standard
deviation $275. Test to see if the population mean costs for the
two types of cruises are different. Use a 1% significance
level.

QUESTION 6 Find the standardized test statistic, z, to test the
claim that p 1< p 2. Use α = 0.10. The sample statistics listed
below are from independent samples. Sample statistics: n 1 = 550, x
1 = 121, and n 2 = 690, x 2 = 195 -2.513 1.116 -2.132 -0.985

A geography test was given to a simple random sample of 250 high
school students in a certain large school district. One question
involved an outline map of Europe, with the countries identified by
number only. The students were asked to pick out Great Britain and
France. As it turned out, 65.8% could find France and 70.2% could
find Great Britain. Is this difference statistically
significant?

The seniors in two high school classes have been asked about
whether they intended to apply to the local state college. The
first class has 13 out of 40 students said they would, as did 20
out of 45 students in the second class.
Is this a significant difference?
Set up a test for the difference of the proportions being equal
to 0 or not.

A random sample of 200 freshman and 100 seniors at
Ferris High School are asked whether they agree with a plan to
excuse upper class students (juniors and seniors) a half hour early
while keeping underclass students (freshmen and sophomores) in
school for the last half hour. Of the students sampled, 160
freshmen opposed the plan and 20 seniors opposed the plan.
Is there a difference (5% level of significance) between the
proportion of freshmen who oppose the plan and...
