Question 1197267
<font color=black size=3>
Answer: <font color=red>d. Reject the null hypothesis</font>



Reason:
The critical values are z = +/- 1.96 aka {{{z = "" +- 1.96}}}
This breaks down into z = -1.96 and z = 1.96


If the test statistic is between those critical values, then we aren't in the rejection region. 
Otherwise if z < -1.96 or z > 1.96, then we are in the rejection region.


In this case, the test statistic z = 2.33 is to the right of the critical value 1.96
We're in the rejection region for this two-tailed test and we therefore reject the null.
