95%
of organs will be between what weights?
(b) What percentage of organs weighs between
305
grams and
335
grams?
(c) What percentage of organs weighs less than
305
grams or more than
335
grams?
(d) What percentage of organs weighs between
290
grams and
335
grams?

What does theory tell us about the effects of unskilled labor migration into a particular region?Specifically, discuss the intra-regional effects of this immigration on unskilled wages, product mix, and the returns to other factors (including, possibly, skilled labor, capital, and/or land). In your answer, contrast the predictions of the specific factors model with those of the Heckscher-Ohlin model, and state the assumptions you are invoking when discussing each. Finally, drawing on readings and class discussions, summarize the empirical evidence on these predictions.

Navigate to the threaded discussion and respond to the following prompts: How might you tolerate differences in ethical views of the work your agency does? What empirical evidence is there to support the ways in which your agency approaches social problems? What might get in the way of truly listening to and learning from others whose opinions about social problems might be different from yours? How do you plan to remain optimistic that social problems can be addressed, reduced, or eliminated?

A researcher studying frogs is investigating the distance that a certain species of frog can jump. The jump lengths appear to be approximately normally distributed with a mean of 85 inches and a standard deviation of 10 inches. Directions: Make a sketch of the "empirical rule" for this setting. a) What proportion of frog jumps are less than 75 inches? b) What jump lengths represent the middle 95% of frog jumps? Between and c) What is the probability of observing a random frog jump that is longer than 105 inches?
