<u>Answer:</u>
C (third figure from left)
<u>Step-by-step explanation:</u>
The spirals in the first, second, and fourth figures are all clockwise from the outer end, i.e., if you trace these three spirals with your finger from the outside to the inside, your finger will move clockwise.
However, if you did the same with the third figure, you would see that the spiral is anti-clockwise from the outside moving in.
Therefore, the third figure doesn't belong.

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:
A) 14
Step-by-step explanation:
Take the width: 6 and multiply it 3 times because it says triple.
That gives you: 6 * 3 = 18
Then subtract 4 because it says four inches less than.
That gives you: 18 - 4 = 14
