Answer:
-78
Step-by-step explanation:
Zinc group :
Mean, x1 = 3328
σ1 = 640
Sample size, n1 = 28
Placebo group :
Mean, x2 = 3406
σ2 = 851
Sample size, n2 = 31
The point estimate for the true difference between the population means is obtained as :
Mean difference between population :
x1 - x2 = 3328 - 3406 = - 78
Answer:a
Step-by-step explanation:
Answer: Point A represents Q1, Point B represents the Median, Point C represents Q3
Step-by-step explanation:
Area of frame=area of total-area of inside ting
area=lenght times width
so
inner one
length is 16-2-2 (both sides) or 12
width or height is 9-2-2=5
so area is 12 times 5=60
outter one
16 by 9
16 times 9=144
so
outer-inner=144-60=84
so 2nd option
Answer:
The unit rate
of the graph is 4, the slope of the graph is 4, and the comparison between answers is that they are equal.
Step-by-step explanation:
For every increase of 1 in the X value of the graph, the Y value increases by 4, so the slope would be
or 4.
