Two separate samples are being used to estimate the difference between population means for two treatment conditions. Which of the following would produce the widest confidence interval?
O a. ni =n2 = 20 with a pooled variance of 10
O b. ni =n2 = 10 with a pooled variance of 100
Oc. n,=n2 = 10 with a pooled variance of 10
d. n, -n2 = 20 with a pooled variance of 100

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

54.864 meters

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
