Which of the following is NOT true of the goodness-of-fit test? Choose the correct answer below. A. Expected frequencies need not be whole numbers. B. If expected frequencies are not all equal, then we can determine them by Eequals=np for each individual category, where n is the total number of observations and p is the probability for the category. C. If expected frequencies are equal, then we can determine them by Upper E equals StartFraction n Over k EndFractionE= n k, where n is the total number of observations and k is the number of categories. D. Goodness-of-fit hypothesis tests may be left-tailed, right-tailed, or two-tailed.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
