There are 68% of students drive to school in one university. Here is a sample of 20 students.
1) What is the probability that only 12 students drive to school?
2)What is the probability that no more than 15 students drive to school?
3) What is the probability that no more than 10 students drive to school?
4) What is the mean and standard deviation?
5) What is the percentage falling with 1 standard deviation? Does it satisfy the Empirical Rule?
Please explain with reasoning/steps please.

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.
