Yes cause the passage is from the new correct one story
Answer:
CI=[0.8592,0.9402]
Yes, Method appears to be effective.
Step-by-step explanation:
-We first calculate the proportion of girls born:
Since np, we assume normal distribution and calculate the 99% confidence interval as below:
Hence, the confidence interval is {0.8598, 0.9402]
-The probability of giving birth to a girl is 0.5 which is less than the lower boundary of the confidence interval, it can be concluded that the method appears to be effective.
A. You add. Hopefully this is right
The answer is A>794 just multiply the total number by 0.32
Answer:
y = - 1
Step-by-step explanation:
The solution to a system of equations given graphically is at the point of intersection of the 2 lines.
The point of intersection = (4, - 1 ) ← solution
with the value of the solution being y = - 1
