Answer:
a) The test is left-tailed.
Step-by-step explanation:
a) Hypothesis testing is tagged two-tailled if the test checks for a claim in both directions (greater than and less than).
It is one tailed if it checks for a claim in only one direction (either greater than or less than). It is left-tailed of it is testing the claim in a less than direction and right-tailed if it is testing the claim in a greater than direction.
This question is to check results from a test of the claim that less than 8% of treated subjects experienced headaches. It is evidently left tailed.

Answer:
The value of the expression 
is equal to 1
Step-by-step explanation:
You can get this answer two ways:
1. Simply plug in into your calculator exactly as it appears. You will get one, so therefore, the expression is equal to 1.
2. If you know your exponent rules, you'll know that anything to the power of 0 equals 1, so no matter the value in the parentheses, the answer will be equal to 1.
Hope this helps!
2, 3, 4, 6, 8, 9, 12, 18, 24, 36
<span>y=15.2-0.537x substitute 9 for y
9</span><span>=15.2-0.537x add .537x to both sides and subtract 9 from both sides
.537x =6.2 divide both side by .537
x= 11.545 round it to 12</span>
