To find $f^{-1}(x)$, let $y = f(x)$ and solve for $x$, $y = x^3 - 2$ $x = (y + 2)$ Interchange $x$ and $y$ in the expression for $x$. $y = (x + 2)$ Find $f^{-1}(x)$ by replacing $y$ with $f^{-1}(x)$. $f^{-1}(x) = (x + 2)$
Solve (3)/(x)=(x)/(3). Give all solutions as a list of numbers separated by comma, if more than one.
You are planning to evaluate the mean of a single continuous variable from a study with a sample of n = 50 using the t statistic. What are the degrees of freedom for the sample? 51 49 50 48 With another study, where you also plan on evaluating a mean using the t statistic, you have a sample of n = 16 that has an SS of 120. What is the variance for the sample? 14,400 8 10.95 2.83 For a sample of n = 36 that has a sample variance of 1,296, what is the estimated standard error for the sample? 6.09 36 37 6

According to your reading, abnormal psychology (or, psychopathology) is the scientific study of abnormal behavior; its goal is to predict reliably, explain, diagnose, identify the causes of, and treat maladaptive behavior. True False
For any non-zero real constant \( \alpha \), it can be shown that \( \int_{-\infty}^{\infty} e^{-(x+i\alpha)^2} dx = \int_{-\infty}^{\infty} e^{-x^2} dx \). Use this result to show that the Fourier transform of \( f(x) = e^{-a^2x^2} \) is \( \frac{C}{a} e^{-\frac{k^2}{4a^2}} \), where \( C = \int_{-\infty}^{\infty} e^{-u^2} du \). Now use the inversion theorem to show that \( C = \sqrt{\pi} \).
