0.0000
Unusual
Step-by-step explanation:
Given that a tobacco company claims that the amount of nicotine in its cigarettes is a random variable with mean 2.2 mg and standard deviation .3 mg.
i.e. population parameters are
The approximate probability that the sample meanwould have been as high or higher than 3.1
=0.0000
Cross multiply
18 / X = 2.4 / 28
so
18 * 28 = X (2.4)
and that becomes
504 = X * 2.4
then divide by 2.4
X = 210
The answer is B. The actual reciprocal is 7/2, since the answer means isn't there its means the reciprocal of the negative or positive sign
50%
The very left point on the box of a box plot is the first quartile, the very right. The very left and right points are the minimum and maximum and the middle line is the second quartile. Since quarters each equal 25%, two quartiles, the data between the first and third quartile, would equal 50%. This is also evident by looking at the graph itself in this problem.
