Answer: One tail test.
Step-by-step explanation:
Given : A sample of 36 observations is selected from a normal population. The sample mean is 12, and the population standard deviation is 3.
Also, The set of hypothesis to conduct a test :-

The kind of test need to perform is dependent upon the alternative hypothesis.
Since, the alternative hypothesis is one tailed (right-tailed), so the test is one tail test.
X = 1/3 yz
3x = yz
y = 3x/z

<h2>Question:</h2><h3>WHAT IS THE NAME YOU OF A SOLID THAT HAS TWO PARRALLEL POLYGON BASES AND ALL OTHER FACES THAT ARE RECTANGLES 2 SEE ANSWERS?</h3>
Step-by-step explanation:
<h3>A prism is a three-dimensional figure with two</h3>
<h3> parallel, congruent bases. The bases, which are</h3>
<h3> also two of the faces, can be any polygon. The </h3>
<h3>other faces are rectangles. A prism is named </h3>
<h3>according to the shape of its bases.</h3>
The value of x is 0.65
<u>Step-by-step explanation:</u>
This solution is given by solving the given problem using BODMAS rule.
This means that the steps to be followed to find the solution should be in the order of BODMAS rule.
B- Bracket, O- of, D- Division, M- Multiplication, A- Addition, S- Subtraction.
This rule states that the 1st operation must be done for Brackets.
⇒ -3.75+2(-4x+6.1)-3.25 = 0
⇒ -3.75 -8x + 12.2 -3.25 = 0
The addition operation should be performed next and then followed by subtraction.
⇒ -8x -7+ 12.2 = 0
<u>To find the value of x :</u>
Keeping the x term alone on one side and moving the constants on other side,
⇒ -8x = -12.2 + 7
⇒ -8x = -5.2
⇒ x = 5.2/8
⇒ x = 0.65
