They are not needed until Sunday night or Monday.

Hi,

I am checkng the questions again but most of them has remaining parts that i do not see.

I see only the first part of the questions, that way i can`t do them all

Also i see that some questions have a lot of parts

Can you upload the remaining parts or you have to answer

the first part to do them ?

Let me know

Thanks

It seems that I have to answer each one at a time on some questions.

If we start now, can you upload the remaining parts ?Since it`s a lot of work can i do 1 to 8 here and 9 to 15 into a new post ?Thanks

ok thanks

ok

z<-2.575 or z>2.575 probability that type I error will be made

a=??

The site will not let me upload screenshot the answer for

3a = b sketch

3a = z,-1.645 was a=0.05

3b = sketch b

3b = z<-2.575 or z>2.575 was a = ???

excellent

4a?

a. z <? or a> ?

b. ? < z < ?

c. z < ?

d. z > ?

6a?

Interpret the results of the test. Choose the correct interpretation below

a. There is sufficient evidence to indicate the true population mean is smaller than 100 at a=0.05

b. There is sufficient evidence to indicate the true population mean is greater than 100 at a= 0.05

c. There is sufficient evidence to indicate the true population mean is not equal to 100 at a= 0.05

Please remember I will gladly tip twice what is asked for your time in this matter.

b. Test the null hypothesis that μ=100 against the alternative hypothesis that μ≠ 100, using a= 0.05. Interpret the results of the test

a. Hο is rejected

b. Hο is not rejected

a. there is sufficient evidence to indicate μ is greater than 100 at a=0.05

b. there is sufficient evidence to indicate μ is not equal to 100 at a=0.05

c. there is insufficient evidence to indicate μ is smaller than 100 at a=0.05

answer is b. there is insufficient evidence to indicate u is not equal to 100 at a=0.05 that was my fault for typing wrong.

compare the results of the two tests you conducted. Explain why the results differ. choose the correct answer below.

a. the results do not differ because these two tests are equivalent

b. the results differ because the alternative hypothesis in part b is more specific than the one in part a.

c. the results differ because the alternative hypothesis in part a is more specific than the one in part b.

correct

Ok,The site was down ....answer for question 7)a) FDo you have options for part b) ? how many decimal places you need ?Thanks

z= two decimal places as needed

What is the appropriate conclusion at a=0.10?

a. reject Ho. there is sufficient evidence to indicate that μ < 29

b. reject Ho. There is insufficient evidence to indicate that μ < 29

c. do not reject Ho. there is sufficient evidence to indicate that μ<29

d.do not reject Ho. there is insufficient evidence to indicate that μ<29

yes ended

What is the rejection region for the test? Choose the correct answer below

a. z>1.645

b. z>1.96

c. z< -1.96

d. z<-1.645 or z>1.645

e. z<-1.645

f. z<-1.96 or z >1.96

what is the value of the test statistic?

z=??? two decimal places

What is the appropriate conclusion at a=0.05?

a. do not reject the Ho. there is insufficient evidence to conclude that the area sampled is not grassland

b. reject Ho. there is sufficient evidence to conclude that the area sampled is not grassland

c. reject Ho. there is insufficient evidence to conclude that the area sampled is not grassland

d. do not reject the Ho. there is sufficient evidence to conclude that the area sampled is not grassland

I will most definitely ask tomorrow morning if you have time. thank you for all your help.

Thank you very much, I will see you at or around 4-4:15 est.
