Answer:
if the village is of 120 people and 120 people are over the age of 60 then 0 people are under the age of 25.
Step-by-step explanation:
Answer:
x is 6 because
y is 30
p is 120
Step-by-step explanation:
60 degrees and 10x are the same and 6×10 = 60
(4y) and 60 degrees must equal 180 so y has to be 30
(4y) and p are the same
Answer:
Answer: 36,000 would be 20 percent. 72,000 would be 40 percent. Step-by-step explanation: You just divide 36,000 by 180,000
Answer:
Z=11.0
Step-by-step explanation:
Let Caucasian individuals be the population 1 and African American be the population 2. So, we are given that
n=150
n1=75
mean1=xbar1=6.1.
standard deviation1=S.D1=σ1=1.1.
Variance1=V(x1)=σ1²=1.1²=1.21.
n2=75.
mean2=xbar2=4.3.
standard deviation2=S.D2=σ2=0.9.
Variance2=V(x2)=σ2²=0.9²=0.81.
The z-statistic is





Z=10.97
Z=11.0
So, the z value obtained while calculating the test statistic is approximately 11.0.
