Answer:
Step-by-step explanation:
Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.
From the above we find that population proportion is 0.03 and observed sample proportion is 0.04
So option a) is wrong
b) Correct
c) correct
d) Wrong
e) wrong
f) wrong
g) incomplete sentence
h) wrong
< MSR = 180 - 110 = 70 degrees
So MR is opposite 70 degrees and MS is opposite 60 degrees
therefore MR is longer than MS

Answer:
Population = All registered voters in Raleigh city
Population size = 9500
Sample size = 360
Proportion of sample statistic for brown = 0.3167
3008 voters
Step-by-step explanation:
Population refers to all elements which meets the requirement for a specific experiment or research interest.
Number of voters for brown = 114
Number of voters for Feliz = 210
Undecided = 36
Sample statistic for proportion in support of brown :
Proportion = x / n
x = number who said they'll vote for brown
n = sample size
Sample statistic for proportion in support of brown = 114 / 360 = 0.3167
Using the proportion ; number from population who'll vote brown :
Sample proportion * population size
0.3167 * 9500 = 3008 voters
The value is 0.02
If it is a negative number, you move the decimal over to the left. :)
