Answer: If a quadrilateral is a square, then it is a rectangle. (choice D.)

Step-by-step explanation:

The Law of Syllogism states that if the following two statements are true: If p , then q . If q , then r . Then we can derive a third true statement: If p , then r .

We can apply this rule in the conditional statements:

<em>If a quadrilateral is a square, (p) then it has four right angles. (q)</em>

<em>If a quadrilateral has four right angles, (q) then it is a rectangle. (r)</em>

Therefore:

<em>If a quadrilateral is a square, (p) then it is a rectangle. (r)</em>

Molybdenum rods are produced by a production line setup. It is desirable to check whether the process is in control, i.e. equal
ikadub [295]

Answer: Test statistic = -8 and rejected region is  (-∞,-1.966) and (1.966, ∞)

Step-by-step explanation:

Since we have given that

X is the length of a rod.

Sample Mean = 2 inches

Standard deviation = 0.5 inches

n = 400

Hypothesis are

H_0:\mu=2.2\\\\H_1:\mu\neq 2.2

Test statistics would be

t=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}}\\\\t=\dfrac{2-2.2}{\dfrac{0.5}{\sqrt{400}}}\\\\t=-8

Degrees of freedom = n-1 =400-1 =39

and \alpha =0.05\\\\\dfrac{\alpha }{2}=\dfrac{0.05}{2}=0.025

Using the t-distribution table, we get that critical value z = 1.966

Since the two tail test will be applied to this,

So, the acceptance region will be (-1.966, 1.966)

Hence, the rejected region will be (-∞,-1.966) and (1.966, ∞)
