You have a graph with a y and a x axis. The x axis is horizontal, the y axis is vertical. first you find the x intercept, which is 4. So you go along the horizontal line until you come across the number 4. draw a point there. Now, you do the same with the y imtercept, accept now you will draw a point at three along the vertical line. draw a straight line connecting the two points. Now, in order to find the slope, you need to know this equation: RISE OVER RUN. What this means, is what it takes to get from one point to another. So, you go to your y intercept. from there, you count downwards, until you have reached the height of the point on the x axis. that is -3. So the rise is negative three, what's the run? Well, now you need to count how many units it takes to get to the other point. you need to go backwards 4 units. so, your rise over run = -3/-4. Since slope = rise/run, Slope = -3/-4, or -(3/4)

Tricky but not crazy hard. You could use th x/y method where you turn it into a cross multiplication fiasco.

or you can try your guesses through what ever equals 1/2 when you add one to the denominator. the answer you are looking for is 2/3

2/3 + 1 for the numerator = 1.

2/3 + 1 for the denominator = 1/2.

Marat540 [252]

Answer:

P value is 0.1932

conclusion is that find value P greater than hypothesis test at the 0.05 level

Step-by-step explanation:

Given data

registered organ donors P  = 40%

sample n = 200

registered organ donors x = 74

hypothesis test α = 0.05

to find out

P-value and state a conclusion

solution

we take a trail p less than 40 % i.e 0.40

so p = x/n

p = 74 / 200 = 0.37

so we find here Z value  i.e

Z = p - P / √(PQ/n)

here Q = 1-p = 1-0.40 = 0.60

so Z = 0.37 - 0.40 / √(0.40×0.60/200)

Z = - 0.866

so p value for Z (-0.866) from z table

P value is 0.1932

and conclusion is that find value P greater than hypothesis test at the 0.05 level
