Most engaged couples expect or at least hope they will have high levels of marital longevity. However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital longevity. (Data source: These data were obtained from the National Center for Health Statistics.) Suppose a sociologist sets out to study the role of race in relationship longevity. She measures relationship longevity in a random sample of African American couples and in a random sample of Latino couples and compares the data. Assume that relationship longevity is normally distributed and that the variance in longevity is approximately the same among African American couples as among Latino couples. Step 1: Do the data meet the test requirements? A. Is there independent random sampling? No Yes B. What is the level of measurement of the variables? Nominal Interval-ratio Ordinal C. Is the sampling distribution normally distributed? Yes No Step 2: State the null hypothesis.

Practice: The Mean and Variance of Binomial Distribution 2 puntos posibles (calificados) Recall that the pmf of a Binomial distribution Binom ($n, p$), with known $n$ can be written as: $f_\theta (y) = \exp \left( \frac{y\theta - b(\theta)}{\phi} + c(y, \phi) \right)$. Refer to the answer of $b(\theta)$ and $\phi$ to the problem Practice: Binomial Distribution as a Canonical Exponential Family 2 pages before this one. Compute $b'(\theta)$. $b'(\theta) = $ (Is this equal to E[Y]?) Compute $\phi b''(\theta)$. $\phi b''(\theta) = $ Note: Express your answers in terms of the canonical parameter $\theta$.
