Zara is conducting research on ring-tailed lemurs and collects the following data on the lengths of tails in cm for 11 full-grown females in a particular group. 62 59 57 60 61 58 63 56 57 57 60

Given that these lengths are normally distributed in the entire population, what is the width of the 95% confidence interval for the mean length? Give your answer as a single number rounded to three significant figures.

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 b suppose 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 c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
