Answer:
2.6549
Step-by-step explanation:
Since the sample size n=65, the degrees of freedom is n-1=65-1=64
The critical value=
Using the t-table and selecting df=64 and 
since it’s a 2 tail the corresponding t-score is 2.6549
Therefore, the critical value is 2.6549
The boundary line should be solid because it have a 'great/less than or equal to' sign

Answer: 0.157</h3>
========================================================
Explanation:
Convert the fraction 9/50 to decimal form. You can use either long division or a calculator.
You should find that 9/50 = 0.18 which is the same as 0.180
So the original compound inequality is the same as saying 0.125 < x < 0.180
This tells us that x is between 0.125 and 0.180 where x is not equal to either endpoint. We simply need to pick anything in this interval. It can be anything you want (I recommend to use a number line to help pick a value). One such value is 0.157. There are infinitely many values you can select from.
The number 0.157 is between 0.125 and 0.180, ie 0.125 < 0.157 < 0.180
It's very similar to saying 157 is between 125 and 180, ie 125 < 157 < 180.
1-31= -30.
Taking an absolute value makes any value positive, so -30 becomes 30.
The absolute value of 1-31 is 30.
