Answer:
The probability that the sample proportion will be at least 3 percent more than the population proportion is 0.6157
Step-by-step explanation:
We need sample proportion between 0.75 - 0.03 = 0.72 and 0.75 +0.03 = 0.78. Here we have p = 0.75 and n= 158.
So z-score for sample proportion q = 0.72
z = 
= 
= - 
= - 0.872
So z-score for sample proportion q = 0.78
z= = 
= = 0.872
Therefore the probability that the sample proportion will be within 3 percent of the population proportion is
P( 0.72 < q < 0.78) = P ( -0.872 < z < 0.872)
= P( z < 0.872) - P( z < -0.872)
= 0.80785 - 0.19215
= 0.6157
You would divide 1/16 by 3/8
Both the mean and median
Median 80+88= 168/2= 84%
Mean 504/6= 84%
73%,
76%,
80%
88%,
90%,
97%,
Answer:
Option B. Range of the given sample data is 113.
Step-by-step explanation:
The given question is incomplete; here is the complete question.
Find the range for the given sample data.
The amounts below represent the last twelve transactions made to Juan's checking account. Positive numbers represent deposits and negative numbers represent debits from his
account.
$28 -$20 $67 -$22 -$15 $17 -$38 $41 $53 -$13 $30 $75
Option A. $75
Option B. $113
Option C. $37
Option D. -$113
Transaction done by Juan can be arrange from lowest to highest
-38 -22 -20 - 15 -13 17 28 30 41 53 67 75
Now we know rage of the sample data = Highest value - Lowest value
= 75 - (-38)
= 113
Therefore, range of the given sample data is 113.
Option B is the answer.
Answer:
c
Step-by-step explanation:
negative and positive make a negative so it cant be 16 it has to be -16
