Answer:
C.-2.33
Step-by-step explanation:
We are given that
Significance level,
%=0.01
We have to find the critical value of z for a left-tailed test.
To find the critical value , we will use the z-table at significance level 0.01 for left-tailed test.
By using the z-table at significance level 0.01 for left-tailed test
The critical value of z at 1% significance level for left-tailed test
=-2.33
We get p-value by using z-critical value
P-value=0.0099<0.01
So, hypothesis test would be reject the null hypothesis at at 1% significance level.
Hence, the critical value of z=-2.33
Option C is true.
Answer:
A. 
Step-by-step explanation:
We are given the inequality, 
On simplifying, we get,

i.e. 
i.e. 
i.e. 
i.e. 
Thus, the solution of the inequality is
.
Hence, option A is correct.
