Answer:
H0: mu = 100
Ha: mu > 100
It is preferable to use this Ha than mu < 100 because it meets the specifications.
Step-by-step explanation:
It is preferable to use mu > 100 as the alternate hypothesis than mu < 100 because the specifications state that mean strength of welds should exceed 100 lb/in^2.
Exceed is expressed using the inequality, greater than.
Therefore, the alternate hypothesis should be expressed using greater than.
<span>The property that is shown in the expression given in the question is commutative property. The word commutative has basically been taken from the word "commute". This means moving around and in case of this problem, it means moving around for doing the addition and getting to the right answer. I hope it helps you.</span>

Answer:
4, 10, 8, 6
Step-by-step explanation:
we have
-------> inequality A
The solution of the inequality A is the interval------> (-∞,-2)
All real numbers less than
-------> inequality B
The solution of the inequality B is the interval------> [4,∞)
All real numbers greater than or equal to
The solution of the compound inequality A or B is equal to
Solution A+Solution B
(-∞,-2) U [4,∞)
therefore
