Question

Test the hypothesis that the proportion of students who wish OBAMA was still president=.3. Use a .10 significance level, a two-tail test, and the following data: A sample of 100 students has 40 who wish OBAMA was still president

**NB: Please can you tell me the table for Z
critical Value, Table for P-Value, Table for T critical Value,
Table for x^2(that is X raise to power 2) Please this is a
self-trained student. I have been trying to get the table with the
solution I have but I could not figure it out.) I will really
appreciate if you can give me the example of each table with the
degree of freedom and Z alpha.**

**Thanks so much**

Answer #1

Here claim is that the proportion of students who wish OBAMA was still president=0.3

So hypothesis is vs

Now

Hence test statistics is

P value is

As P value is less than alpha=0.10 we reject the null hypothesis

Hence we do not have sufficient evidence to support the claim that p=0.3

Regarding tables i would suggest you can use only calculators which are available to compute the required critical values and P value. Just google it you will receive all of them.

How much sleep are students really getting? You wish to know the
true mean hours of sleep for all students at WSU on any given
school night. You survey 64 students and find that the sample
average is 5.3 hours of sleep. With a known standard deviation of 5
hours and a level of significance of 1%, is the population mean
hours of sleep for students at WSU different than 7 hours?

Use the appropriate test to determine if the effect of galleys
for a manuscript (X) on the total dollar cost of correcting
typographical errors (Y) in technical manuscripts can be
justifiably represented by a regression-through-the-origin model.
Find (i) value of the test statistic, (ii) critical value at 2%
level of significance, and (iii) p-value of the test. The linear
regression function does through the origin, the estimated
regression function is Y-hat=18.0283X

i. A researcher estimated the proportion of voters who favor the
Democratic candidate in an election. Based on 500 people she
calculates the 95% confidence interval for the population
proportion p: 0.123 <p<0.181.
Which of the following is a valid interpretation of this
confidence interval ?______
a. There is a 95% chance that the true value of p lies between
0.123 and 0.181
b. If many different samples of 500 were selected
and a confidence interval was constructed based on...

A group of Psychology students was interested in writing a paper
for their research class
concerning the difference between girls and boys and their
friendships. They determined
to study primary school aged children on the playgrounds of
schools. They hypothesized
that girls would pursue narrower, more intense friendship groups
than boys, that is, they
would interact with fewer other children than would the boys on
average. They selected
30 boys and 30 girls to watch at their schools. On average...

Some students are good in mathematics and others are better at
reading or writing. The question is whether there is any
relationship between a student’s ability in math and his/her
ability in reading or writing. The SAT, a standardized test for
college admissions that is widely used in the United States, has
three sections, Math, Critical Reading, and Writing. The table
below contains SAT Math, Writing, and Critical Reading test scores
for 20 randomly chosen students accepted by a university....
