A study was conducted to measure the effect of a fungicide treatment on the survival rate of botrytis blight. Botrytis blight samples were divided into 20 groups, each consisting of about 100 samples and exposed to different levels of chemicals in a fungicide. The output of a logistic regression model is below, where concS represents the concentration of a sulfur in the fungicide and concCu represents the concentration of a copper in the fungicide. Required:
a. What is the probability of survival for a botrytis blight sample exposed to a sulfur concentration of 0.7 and a copper concentration of 0.9?
b. Suppose you wanted to test if the coefficient for concCu is equal to -0.2. What z-value would you use for this test?
c. Construct an approximate 95% confidence interval for the coefficient of concCu.

step-by-step explanation:

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.
