Answer:
Option A
Explanation:
The complete question is
Consider a researcher who is conducting final clinical trials to validate that a new treatment for anxiety is effective. This researcher is extremely focused on avoiding mistakes in concluding that this new treatment is effective when it really is not when conducting their research. What should this researcher do?
a. set a low alpha level
b. set a high alpha level
c. set a low sample mean
d. set a high sample mean
Solution
Option A
While carrying out multiple tests, alpha levels are set at low value. In this way value of alpha also reduces. The lower is the value of alpha, the lower will the chances of rejecting a null hypothesis. The chances of type II error increases, which makes it difficult to reject the null hypothesis
Null hypothesis in this case is "New treatment is effective"

The second trapezoid has the length of x as 4.2 cm.

Scaling </h3>
Scaling is the increase or decrease in the size of an object or figure by a factor k, so as to create an image.
Scaling leads to the creation of similar figures. Similar figures have the same shape and the ratio of their corresponding sides are in the same proportion
From the question, since both trapezoids are similar, hence:
14.7 / 4.9 = 12.6 / x
x = 4.2 cm
The second trapezoid has the length of x as 4.2 cm.
