Answer:
A.Because the confidence interval includes zero, the researcher can conclude the proportion of men and women who exercise regularly is the same.
Step-by-step explanation:
When the null value is contained in the confidence interval we tend to fail to reject the null hypothesis.
Here, the hypothesis according to scenario are
Null hypothesis: The Proportion of men and women who exercise regularly is same i.e. p1-p2=0.
Alternative hypothesis: The proportion of men and women who exercise regularly is not the same i.e. p1-p2≠0.
The null value here is 0. As the confidence interval is (-0.154,0.138) and it contains 0, so we fail to reject the null hypothesis and conclude that the proportion of men and women who exercise regularly is the same.

Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
First, we need to find the slope of the line (m)
the equation is (y2-y1)/(x2-x1)
let's label the points
x1=-2
y1=4
x2=2
y2=4
susbtitute into the equation
m=(4-4)/(2--2)
m=0/4
m=0
the slope is 0.
now let's use point slope form: y-y1=m(x-x1)
once again let's subsitute into the equation
y-4=0(x+2)
do distributive property
y-4=0
add 4 to both sides
y=4
the equation is y=4
hope this helps!
