Crazy boy [7]
<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.

Write an equation in standard form of the hyperbola described.
marishachu [46]

Check the picture below, so the hyperbola looks more or less like so, so let's find the length of the conjugate axis, or namely let's find the "b" component.

\textit{hyperbolas, horizontal traverse axis } \\\\ \cfrac{(x- h)^2}{ a^2}-\cfrac{(y- k)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h\pm a, k)\\ c=\textit{distance from}\\ \qquad \textit{center to foci}\\ \qquad \sqrt{ a ^2 + b ^2} \end{cases} \\\\[-0.35em] ~\dotfill

\begin{cases} h=0\\ k=0\\ a=2\\ c=4 \end{cases}\implies \cfrac{(x-0)^2}{2^2}-\cfrac{(y-0)^2}{b^2} \\\\\\ c^2=a^2+b^2\implies 4^2=2^2+b^2\implies 16=4+b^2\implies \underline{12=b^2} \\\\\\ \cfrac{(x-0)^2}{2^2}-\cfrac{(y-0)^2}{12}\implies \boxed{\cfrac{x^2}{4}-\cfrac{y^2}{12}}
