Answer:
0.4967<p<0.6033
Not effective
Step-by-step explanation:
given that a clinical trial tests a method designed to increase the probability of conceiving a girl.
In the study 580 babies were born, and 319 of them were girls
Sample proportion p=
Standard error of proportion p =
Margin of error for 99%= Z critical * std error=
(Since sample size is large Z value is used)
Confidence interval 99%
=
0.4967<p<0.6033
This method appears to be not effective as the confidence interval 99% contains 0.50 indicating probability for girls is still 0.50
Answer:
y = 8
Step-by-step explanation:
adjacent/hypotenuse = cos(x)
4 / y = cos(30)
y = 4 /cos(30)
y = 8
X= 270
simplify the equation using cross multiplication
Mid-point of a segment having extreme ends as (h, k) and (p, q) is given by,
If the coordinates of the extreme ends are Q(1, 6) and R(-7, 3),
Mid-point of the segment QR will be,
Therefore, mid point of the segment QR will be .
