Question

A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 713 women and 613 men were independently and randomly selected, and that 338 women and 244 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2 )? Use a significance level of α=0.1 for the test.

**Step 1 of 6 : State the null and alternative hypotheses
for the test.**

**Step 2 of 6 : Find the values of the two sample
proportions, pˆ1 and pˆ2. Round your answers to three decimal
places.**

**Step 3 of 6 : Compute the weighted estimate of p‾. Round
your answer to three decimal places.**

**Step 4 of 6 : Compute the value of the test statistic.
Round your answer to two decimal places.**

**tep 5 of 6 : Find the P-value for the hypothesis test.
Round your answer to four decimal places.**

**Step 6 of 6 : Make the decision to reject or fail to
reject the null hypothesis.**

Answer #1

A Gallup poll to survey the top concerns of Americans was
conducted. Suppose that 713 women and 613 men were independently
and randomly selected, and that 338 women and 244 men chose the
state of the economy as their biggest concern. Can we conclude that
the proportion of women ( p1 ), choosing the state of the economy
as their biggest concern, exceeds the proportion of men ( p2
)? Use a significance level of α=0.1 for the test.

A Gallup poll to survey the top concerns of Americans was
conducted. Suppose that 366366 women and 422422 men were
independently and randomly selected, and that 202202 women and
186186 men chose the state of the economy as their biggest concern.
Can we conclude that the proportion of women ( p1p1 ), choosing the
state of the economy as their biggest concern, exceeds the
proportion of men ( p2p2 )? Use a significance level of
α=0.05α=0.05 for the test.

A Gallup poll to survey the top concerns of Americans was
conducted. Suppose that 387 women and 359 men were independently
and randomly selected, and that 239 women and 202 men chose the
state of the economy as their biggest concern. Can we conclude that
the proportion of women (p1), choosing the state of the economy as
their biggest concern, exceeds the proportion of men
(p2)? Use a significance level of α=0.01 for the
test.

results:
n1= 350 n2= 475
pˆ1=0.55 pˆ2=0.68

In a survey of 350 childless married couples who were asked if
they plan to have children in the next 55 years, 18% of the men and
10% of the women responded "Yes". Based on this survey, can it be
concluded that there is a difference in the proportion of men ( p1)
and women ( p2 ) responding "Yes"? Use a significance level of
α=0.05 for the test.

The manufacturer of a new racecar engine claims that the
proportion of engine failures due to overheating for this new
engine, (p1), will be no higher than the proportion of engine
failures due to overheating of the old engines, (p2) . To test this
statement, NASCAR took a random sample of 115 of the new racecar
engines and 110 of the old engines. They found that 13 of the new
racecar engines and 7 of the old engines failed due...

A salesman for a new manufacturer of cellular phones claims not
only that they cost the retailer less but also that the percentage
of defective cellular phones found among his products, ( p1 ), will
be no higher than the percentage of defectives found in a
competitor's line, ( p2 ). To test this statement, the
retailer took a random sample of 130 of the salesman's cellular
phones and 105 of the competitor's cellular phones. The retailer
found that 12 of...

The U.S. Census Bureau conducts annual surveys to obtain
information on the percentage of the voting-age population that is
registered to vote. Suppose that 665 employed persons and 652
unemployed persons are independently and randomly selected, and
that 379 of the employed persons and 261 of the unemployed persons
have registered to vote. Can we conclude that the percentage of
employed workers ( p1 ), who have registered to vote, exceeds the
percentage of unemployed workers ( p2 ), who...

GfK Research North America conducted identical surveys 5 years
apart. One question asked of women was “Are most men basically
kind, gentle, and thoughtful?” The earlier survey revealed that, of
the 3,000 women surveyed, 2,010 said that they were. The later
revealed 1,530 of the 3,000 women surveyed thought that men were
kind, gentle, and thoughtful. At the 0.05 level, can we conclude
that women think men are less kind, gentle, and thoughtful in the
later survey compared with the...

Given two independent random samples with the following
results:
n1=428 x1=270 n2=251 x2=135
Can it be concluded that there is a difference between the two
population proportions? Use a significance level of α=0.05 for the
test.
Step 1 of 6: State the null and alternative hypotheses for the
test
Step 2 of 6: Find the values of the two sample proportions, pˆ1
and pˆ2. Round your answers to three decimal places.
Step 3 of 6: Compute the weighted estimate of...
