Nonconformities occur in glass bottles according to a poisson distribution. A random sample of 100 bottles contains a total of 11 nonconformities.

(a) Develop a procedure for testing the hypothesis that the mean of a Poisson distribution equals a specified value 0. Hint: use the normal approximation to the poisson.
(b)Use the result of part (a) to test the hypothesis that the mean occurrence rate of nonconformities is =0.15. Use α=0.01

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

slope intercept form is y = mx + b
