An article in the Los Angeles Times (Dec. 3, 1993) reports that 1 in 500 people carry the defective gene that causes inherited colon cancer. In a sample of 2000 individuals, we are interested in the number of individuals who carry this gene. Typically 1 binomial distribution can be used to model this number. However, in the case of large n and small p, we can use Poisson distribution approximately. Answer the following questions using R commands. (a) Use binomial distribution to calculate the the probability that between 5 and 8 (inclusive) carry the gene. (b) Use binomial distribution to calculate the the probability that at least 8 carry the gene. (c) Use Poisson distribution to recalculate the approximated probability for part(a) and make comparison. (d) Use Poisson distribution to recalculate the approximated probability for part(b) and make comparison.

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
