Is there a picture? there's not enough info
I think it’s 5 but i’m not sure lol
P - q i believe because
p = total average
q = average of ac
x = average of bd
p - q = x
A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
50 over 360 * 7.2*pi = 3.14159...
