Question

Please answer the second problem

To be on the safe side, 4000 voters were surveyed and 1300 were in favor of gambling on sporting events. Give a 99% confidence interval for the tur proportion of voters in favor of sports gabling

A. give the null and alternative hypotheses

B Give the critical values of the test

C. Give the test statistic

D. Give the p value

E. Give the type of error you could have made

Assuming the proportions found in problem 2 is the true proportion of all voters in favor of sports gabling test the hypothesis’s that the proportion of students in favor of sports gambling is higher at the a=0.05 significance level. From a recent survey of 500 students. 178 were in favor of sports gabling

A. give the null and alternative hypotheses

B Give the critical values of the test

C. Give the test statistic

D. Give the p value

E. Give the type of error you could have made

Answer #1

2)

A)

null Hypothesis: Ho: | p | = | 0.325 | |

alternate Hypothesis: Ha: | p | > | 0.325 |

B)_ critical values of the test Z=1.645

C) test statistic =1.48

D)p value =0.0694

E) as we fail to reject null hypothesis ; this may lead to type II error

To be on the safe side, 4000 voters were surveyed and 1300 were

interval for the tur proportion of voters in favor of sports
gabling

For your senior design project one of the problems you had to
work on was the yield strength of a steel weld joint created by a
robot. Your test 15 weld joints and found they had an average yield
strength of 270 MPa with a standard deviation of 25MPa. Give a 95%
confidence interval for the true yield strength of the weld joint.
(by the way Mpa is megapascals measure of force in metric units.
1MPa =145.038 psi)

In a recent poll, 134 registered voters who planned to
vote in the next election were asked if they would vote for a
particular candidate and 80 of these people responded that they
would. We wish to predict the proportion of people who will vote
for this candidate in the election.
a) Find a point estimator of the proportion who would vote for
this candidate.
b) Construct a 90% confidence interval for the true proportion
who would vote for this...

A major issue facing many states is whether to legalize casino
gambling. Suppose the governor of one state believes that more than
55% of the state's registered voters would favor some form of legal
casino gambling. survey a simple random sample of 300 voters in the
state. The team decides to use a significance level of 0.05 when
testing their hypothesis.
The data given was 175 yes responses and 125 no responses
1. Choose the appropriate hypotheses:
Ho: p<0.55
Ha:...

A professor surveyed a random sample of 63 students about
whether they planned to take an optional final exam for the course.
Of the 63 students surveyed, 47 indicated that they planned to take
the exam.
(a) Compute the necessary sample size for estimating p
to within .2 with 95% confidence. Use the sample proportion for
this problem.
(b) Construct and interpret a 98% confidence interval for
p, the true proportion of students who plan to take the
final exam....

Suppose there are 145 students enrolled in some major, of which 113
are female. Can we conclude that there is a higher proportion of
female students in this major than at Lehman overall? Use a
significance level of 0.01.
(a) What are the null and alternative hypotheses?
(b) What is the test statistic?
(c) What is the critical value?
(d) Do you reject or fail to reject the null hypothesis?...

After the football team once again lost a game to the college's
arch rival, the alumni association conducted a survey to see if
alumni were in favor of firing the coach. A random sample of 100
alumni from the population of all living alumni was taken. 64 of
the alumni in the sample were in favor of firing the coach. Let p
represent the proportion of all living alumni who favor firing the
coach.
a) Give a 95% confidence interval...
