i really need help.. i just dont understand at all . please explain to me. Thanks in advance.

Assume the value of the population standard deviation is ?=100

what is the p-value of the test?
what is the value of the test statistic that should be used since we now know ??

We can not figure much out with just a standard deviation to go with.

are you saying, it is impossible? its part of my hw unless its a trick question :/

 

[galactus]

Yes, it is. There is not enough information. How can we find a test statistic and all with nothing more than that?.
