A group of researchers want to determine whether type of psychotherapy has an effect on the number of PTSD symptoms in refugees. Specifically, they wan to determine if MDMA, a hallucinogenic drug given in a one-time dose, has a greater effect on reducing PTSD symptoms in refugees than the standard PTSD treatment or a placebo control. The researcher randomly assigns 60 people to 1 of the 3 treatment conditions. What is the alternative hypothesis in notation form? u1 =/ u2 =/ u3 p > 0 u1 = u2 = u3 It cannot be written in notation form.
The option u1 =/ u2 =/ u3 is correct if the researcher randomly assigns 60 people to 1 of the 3 treatment conditions.
What are the null hypothesis and alternative hypothesis?The null and alternative hypotheses are two generalizations about a population that are strictly contradictory. The null hypothesis can be denoted by H₀ and the alternative hypothesis can be denoted by H₁.
We have:

Subpart (e) :
⇒ New volume = 2 x 3 x 2 x 4 x 2 x 5
⇒ New volume = 8 x 60
⇒ New volume = 480 in³
=============================================================
Subpart (f) :
⇒ New volume : Original volume
⇒ 480 : 60
⇒ 1 : 8
=============================================================
Subpart (g) :
Step 1
⇒ SA = 2(6 × 9 + 9 × 11 + 6 × 11)
⇒ SA = 2(54 + 99 + 66)
⇒ SA = 2(219)
⇒ SA = 438 in²
Step 2
⇒ V = 6 × 9 × 11
⇒ V = 54 × 11
⇒ V = 594 in³
Step 3
⇒ New SA = 2 x 438
⇒ New SA = 876 in²
Step 4
⇒ New : Original
⇒ 876 : 438
⇒ 2 : 1
Step 5
⇒ New V = 2³ x 594
⇒ New V = 8 × 594
⇒ New V = 4752 in³
Step 6
⇒ New : Original
⇒ 4752 : 594
⇒ 8 : 1

Rectangle QUAD has coordinates Q(0,0), U(0,), A(,), and D(,0). Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor . What are the coordinates of point D'?
The coordinates of point D' are (36,0).
What is scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures.
QUAD has coordinates Q(0,0), U(0,3), A(6,3), and D(6,0).
The scale factor for Q'U'A'D' is 6.
So, the coordinates of Q'U'A'D' after dilation is:
Q'(0,0), U'(0,3*6), A'(6*6,3*6), and D'(6*6,0).
and Q'(0,0), U'(0,18), A'(36,18), and D'(36,0).
Hence, the coordinate of D' is (36,0).

The statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.
To answert the question, we need to know what an atom is.
What is an atom?An atom is the smallest indivisible part of a substance. It is represented by letters.
It has an atomic number which is the number of protons or electrons present in an atom and is written as a subscript in from of the letter symbol.It has a mass number which is the number of protons plus neutrons in an atom and is written as a subscript in from of the letter symbol.So, since the atom of this radionuclide contains 31 protons and 36 neutrons.
So, its atomic number is 31. Its mass number is number of protons + number of neutrons = 31 + 36 = 67. Its symbol is superscript 67 and subscript 31.
So, the statement is correct about the radionuclide the atomic number is 31, the mass number is 67, and its symbol is superscript 67 subscript 31 baseline upper g a.
