<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.
I think this is right. Hope it helps
Answer:
Step-by-step explanation:
total cost = c
students = s
cost = 7
c = s*7
independent is s
dependent is c
Answer:
Step-by-step explanation:
<u><em>The complete question is</em></u>
A cone and a triangular pyramid have a height of 9.3 m and their cross-sectional areas are equal at every level parallel to their respective bases. The radius of the base of the cone is 3 in and the other leg (not x) of the triangle base of the triangular pyramid is 3.3 in
What is the height, x, of the triangle base of the pyramid? Round to the nearest tenth
The picture of the question in the attached figure
we know that
If their cross-sectional areas are equal at every level parallel to their respective bases and the height is the same, then their volumes are equal
Equate the volume of the cone and the volume of the triangular pyramid
![\frac{1}{3}\pi r^{2}H=\frac{1}{3}[\frac{1}{2}(b)(h)H]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7DH%3D%5Cfrac%7B1%7D%7B3%7D%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29H%5D)
simplify
we have
substitute the given values
solve for x
