<span>a) Explain how you would carry out a completely randomized experiment for the study
- The volunteers will be listed alphabetically and assigned a number from 1 to n. Using the random selection method, select the persons at half of the population and assign them as the treatment group getting the new medication. The remaining population will be under the current medication. Measure everyone's cholesterol level and apply the needed medication for several months. Apply the process and compare the results.
</span><span>b) Describe an experimental design that would improve the design in (a) by incorporating blocking</span><span>
- The best design would be to block by cholesterol levels (ie, High, Moderately High, Very High)
</span> c) Can the experimental design in (b) be carried out in a double blind manner?
Yes, everyone in each block randomly assigned to a treatment so volunteers are not aware of the medication they are receiving while administrators do not know what medication they are giving.
When a transversal crosses a pair of parallel lines same side interior angle pair are supplimentary.
What is angle?
Angle is the space between two intersecting lines or surface at or close to the point where they meet.
Sol-We are given that two parallel lines are intersected by a transversal.
We have to find pair of supplementary angles.
Supplementary angle: Two angles whose sum is equal to 180 degrees are called supplementary angles.
Corresponding angles.
It is not necessary that sum of corresponding angles is always equal to 180 degrees.Therefore, pair of angles are not always supplementary.
Thus it is true.

Answer:
Step-by-step explanation:
In 
O, ST and VT are tangents at points S and V respectively.
In quadrilateral OSTV,
(By interior angle sum postulate of a quadrilateral)
(Measure of minor arc is equal to measure of its corresponding central angle)
(By arc sum property of a circle)
Answer:
48
Step-by-step explanation:
80 divided by 4 is 20 so thats 1/4 of 80
80-20=60
1/5 of 60 = 12
20+12=32
80-32=48
