Answer:
a. t
b. a (or x = a)
c. r
d.
1) c
2) t
3) a
4) p
Step-by-step explanation:
a. Draw vertical line passing through the point (c,0). This line intersects the graph at point L. Point L has coordinates (c,t), so
b. If draw the horizontal line passing through the point (0,p). This line intersects the graph at point K with coordinates (a,p), so
c. Note that then
d. Coordinates of point L are (c,t), coordinates of point K are (a,p)

Answer:
Step-by-step explanation:
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
