Answer. A
Explanation. slope intercept form is y= mx + b. m represents the slope and b represents the y intercept (the point where the line meets the y-axis). We know that the slope is 1/3 but since the y-point is 0, there is no VISIBLE “b” in the equation. The correct solution is A :)
good luck.

Answer:

0.08065

Step-by-step explanation:

Given that in a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to give the number of people in the last six months with whom you discussed matters that are important to you.

If X is random variable then X has mean 2.2 and s = 1.4

n=2006

Std error of mean = $\frac{1.4}{\sqrt{2006} } \\=0.03126$

For 99% since sample size is large, t and z distn almost coincide.

Hence we can take 2.58 as critical value

Margin of error at 99% = $2.58*0.03126\\=0.08065$
