Answer:
take the population mean divided by four
Step-by-step explanation:
(x^2 +5x+2.5^2) +4+5
(x+2.5)^2+9
vertex -2.5,9
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.
The answer is D, (1/3, 4).
