Details CNNBC recently reported that the mean annual cost of auto insurance is 1030 dollars. Assume the standard deviation is 192 dollars. You will use a simple random sample of 52 auto insurance policies.

Find the probability that a single randomly selected policy has a mean value between 1069.9 and 1093.9 dollars.
P(1069.9 < X < 1093.9) =

Find the probability that a random sample of size
n
=
52
n=52
has a mean value between 1069.9 and 1093.9 dollars.
P(1069.9 < M < 1093.9) =

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 > ?
