Question 444138: If the observed value is 8, the expected value is is 5, an the standard error is 2, then the test value used for the z test is equal to what?
If the observed value is 7, the expected value is 8, and the standard error is 2, then the test value used for the z test is equal to what?
For the conjecture "The average rent of an apartment is more than $750 per month", what is the alternative hypothesis?
Is the following a valid null hypothesis? Ho : = 6

You can put this solution on YOUR website! If the observed value is 8, the expected value is is 5, and the standard error is 2, then the test value used for the z test is equal to what?
----
z(8) = (8-5)/2 = 3/2
----------------------------
If the observed value is 7, the expected value is 8, and the standard error is 2, then the test value used for the z test is equal to what?
z(7) = (7-8)/2 = -1/2
----------------------------
For the conjecture "The average rent of an apartment is more than $750 per month", what is the alternative hypothesis?
---
Ans: The average rent is <= 750 per month.
----------------------------------------------------
Is the following a valid null hypothesis? Ho : = 6
It should say u = 6 to be valid.
Ho must be a statement about a population parameter (u or p)
