The chi-square test is appropriate to analyze the primary efficacy endpoint in this study
The chi-square test is a valid statistical hypothesis test when the test statistic is chi-square distributed under the null hypothesis. Specifically, Pearson's chi-square test and its variants. Used to compare observed and expected results. The purpose of this test is to determine whether differences between observed and expected data are due to chance or to relationships between the variables being examined.
A chi-square formula is a statistical formula for comparing two or more sets of statistical data. It is used for data consisting of variables that span different categories and is denoted by χ2. The chi-square formula is χ2 = ∑(Oi – Ei)2/Ei, where Oi = observed (actual) and Ei = expected.

Answer:
15, 9, 3, -3
Step-by-step explanation:
y= -3x+3
for x= -4, -2, 0, 2 substitute in your equation
y= (-3)*(-4)+3= 12+3= 15
y= -3*-2+3 = 6+3 = 9...
Answer:
The image below will explain the question
To figure out the length of portion BC, we will use the trigonometric ratio below
By substituting the values, we will have
Hence,
The final answer is
The FOURTH OPTION is the right answer
A= 26 > q
if it says 26 grader than it means the mouth opens to that 26
if it says 26 less then it means the mouth is facing to the q
but it is not so it is the mouth facing the 26
Answer:
$25
Step-by-step explanation:
Cost = 30 x months + 25
Every month you will pay 30$
At 0 months when you sign up substitute m=0
Cost = 30x 0 +25 = 0 +25 =25
