Answer:
The answer is -8.
Step-by-step explanation:
The absolute value is the distance between a number and zero, and it is always positive. The distance between -8 and 0 is 8. Then, once the absolute value is found, the actual answer needs to be found by multiplying 8 by (-1). Usually the number in front of an absolute value is 1; however, this absolute value has a negative in front of it, which causes the 1 to become a -1. Thus, causing the final answer to be -8.
Answer: 0.866
Step-by-step explanation:
Mean = 4022
SD = 266
We are looking for the probability of samples 45g differ than the mean. Hence 2 probability combination:
X>4067 and X<3977
Calculate for Z we'll get Z = 0.16917 and -0.161917
Using Z formula we can find P(Z=0.17) = 0.433
Since both probability will occupy the same area, total probability is 0.433x2 = 0.866

Answer:
C. 2.937
Step-by-step explanation:
Given the following :
H0 : p = 0.25
H1 : p > 0.25
Number of observations (n) = 647
p' = 30% = 0.3
SD = sqrt[(p(1 - p) / n)]
1 - p = 1 - 0.25 = 0.75
SD = sqrt[(0.25 * 0.75) / 647]
SD = sqrt[0.0002897]
SD = 0.0170234
Z = (p' - p) / SD
Z = (0.3 - 0.25) / 0.0170234
Z = 0.05 / 0.0170234
Z = 2.9371187 = 2.937
