2. a manufacturer of boots plans to conduct an experiment to compare a new method of waterproofing to

the current method. the appearance of the boots is not changed by either method. the company recruits

100 volunteers in seattle, where it rains frequently, to wear the boots as they normally would for 6 months.

at the end of the 6 months, the boots will be returned to the company to be evaluated for water damage.

(a) describe a design for this experiment that uses the 100 volunteers. include a few sentences on how it

would be implemented.

(b) could your design be double blind? explain.

A experimental design could be applied in this case. The experimental design is a technique of research used to identify and quantify causes occurred from a specific effect during a experimental study.

In this case, the variable that cause something is the rain, and the study is gonna be focused on the effects, which are water damages. To do the experiment with this design, first we need to identify specific indicators to observe and measured, like material resistance, water damage, state after the  causal variable is applied.

On the other hand, this design is not needed to be double blind, because that 's applied when the experiment consist in two groups with different stimulations, which is not the case here.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
