Give a power series representation for the function f(x) x^3/(1 + 9x^2)

Nata [24]

Recall that for $|x|$ , we have

$\displaystyle\frac1{1-x}=\sum_{n\ge0}x^n$

Replace $x$ with $-9x^2$ and we get

$\displaystyle\frac1{1-(-9x^2)}=\sum_{n\ge0}(-9x^2)^n=\sum_{n\ge0}(-9)^nx^{2n}$

Lastly, multiply this by $x^3$ , so that

$\boxed{f(x)=\displaystyle\sum_{n\ge0}(-9)^nx^{2n+3}}$

Express the alternative hypothesis in symbolic form. A professor claims that the mean amount of time (in hours) sophomores spen

gulaghasi [49]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Let the $\mu_1$ be the mean amount of time first population ( freshmen) spent studying for the biostatistics final exam.

Let $\mu_2$ be the mean amount of time second population (sophomores) spent studying for the biostatistics final exam.

So, the hypothesis would be

$H_0:\mu_1=\mu_2$

Since, A professor claims that the mean amount of time (in hours) sophomores spent studying for the biostatistics final exam is more than that of freshmen.

So, alternate hypothesis becomes:

$H_a:\mu_1>\mu_2$

Hence, Option 'D' is correct.
