There are various ways of going about the test. I outline one normal approximation method in "Inference for One Proportion: Introduction" and "Inference for One Proportion: An Example".
I'm not going to answer that posted question, but I will tell you that you need to calculate the sample standard deviation from the given information and go from there.
Unfortunately its the sample standard deviation that I do not know how to find, other than that I feel I can complete the question. Would it be possible for you to explain how to get the SD or point me in the right direction?
I've been trying all day to search for that and every site or source says I must have the data set which I do not, I only have the sum of the data set. Unless I am missing something completely obvious. Anyway sorry to bother you and thanks for your time.
Hey there, I've found myself watching a lot of your videos lately. I have a midterm tomorrow and am having trouble with one type of question. The question does not provide with a SD. The question puts me over the the character limit so I will leave it in another comment. If you could possibly help solving this question I would greatly appreciate it!
+Carmen San If we are carrying out inference on a mean of a normally distributed population, and sigma is unknown, we use a t test. I have many videos on t tests.

I'm glad to hear this video helped your understanding. Best of luck on your exam!
I strongly suspect googling 'calculate sample standard deviation' will help.
If I have an alpha of .03 how do I find the rejection region value by using a table
How did you get 1.645 when using a table. How do you find the value manually
did you figure it out?
90% is 0.10/ 2 = 0.05 -> 0.5-0.05 = 0.4500 if you look this up in the table its between 1.64 and 1.65 so you take the average and get 1.645.
You are very welcome!
tomorrow is my final exam and i got deeper understanding watching this, thanks a lot. Goodluck to me! ;)
Glad to be of help.

OMFG this is SO helpful
why do I still go to class instead of staying home and watching RUclips!!!!!!!!!
There are still some benefits of going to class, but I'm glad I could be of help!
thank you very much, i was struggling to understand this and you made it so simple

Super helpful! Thanks JB!

what if sigma is unknown ??

Perfect illustration! Very helpful, thank you.
thanks for the video...very helpful...although i cant shake the image of learning statistics from Seth Rogan when I hear your voice...
Well, you know, Canadians all sound the same on video. Maybe for kicks Seth and I can switch jobs for a month. Cheers.
Bless you.
THANKS! you are a lifesaver :)
thank you, it helped a lot
You are very welcome!
Gee thanks for nothing. Because I can totally use google calculators during exams
PANO NAGING 1.645 YON PAKI EXPLAIN PLEASEEEEEEEEE
