Refer to the study in Example 3. The recovery times (in days) for Group 2 are listed below. Find the sample variance and standard deviation of the recovery times.

43 57 18
45 47 33 49 24

entering that problem on the tube might get you an answer

really your just stupid if you don't know this

step-by-step explanation:

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

step-by-step explanation:

- 4, v72, 32/5

i think this is right.

hope it
