A suitable probability calculator can tell you the probability is about 6.7%.
_____
The standard deviation of the distribution of sample means is the population standard deviation (6) divided by the square root of the sample size (√144=12). Thus, your threshold is about (19.25-20)/(6/12) = -1.5 standard deviations from the mean.
A <em>circle</em> is a figure <u>bounded</u> by a <em>curved</em> side which is referred to as <em>circumference</em>. Thus the area of the <u>shaded</u> region is option D. 81.65.
A <em>circle</em> is a figure<u> bounded</u> by a <em>curved</em> side which is referred to as <u>circumference</u>. Some of its <u>parts</u> are radius, diameter, sector, arc, etc.
The area of a <u>circle</u> can be determined by the given <em>expression:</em>
Area = π
where r is the <u>radius</u> of the circle and π =
So, the area of the <u>shaded</u> region can be determined as:
Area of the <em>shaded</em> region = <em>area </em>of the <u>larger</u> circle - <em>area</em> of the <u>smaller</u> circle
Area of the<em> shaded </em>region = π - π
= π (46.24 - 20.25)
= x 25.99
=
<u>Area</u> of the <em>shaded</em> region = 81.683
Thus the<u> appropriate</u> answer to the question is option D. 81.65.
