Answer:
z = 1.476
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
The answer is z = 1.476
Answer:
q = 5/18
Step-by-step explanation:
q + 5/9 = 5/6
Subtract 5/9 from each side
q + 5/9 - 5/9 = 5/6 - 5/9
q = 5/6 - 5/9
Get a common denominator of 18
q = 5/6 *3/3 - 5/9 *2/2
q = 15/18 - 10/18
q = 5/18
