Calculate the test statistic and p-value for each sample. use appendix c-2 to calculate the p-value. (negative amount should be indicated by a minus sign. round your test statistic to 2 decimal places and p-value to 4 decimal places.)

test statistic p-value
(a) h0: p = .60 versus h1: p > .60, a = .05, x = 56, n = 80
(b) h0: p = .30 versus h1: p ? .30, a = .05, x = 18, n = 40
(c) h0: p = .10 versus h1: p < .10, a = .01, x = 3, n = 100

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

where is the diagram? shown below where? ?

step-by-step explanation:

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
