Using statistical concepts, we have that:
- a. The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.
- b. The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.
<h3>Range and standard deviation:</h3>
- The range of a data-set is given by the difference <u>between the highest value and the lowest value in the data-set</u>.
- The standard deviation of a data-set is given by the <u>square root of the sum of the difference squared of each observation and the mean, divided by the number of observations</u>.
Item a:
- The lowest value is of 0.
- The highest value is of 6.
Hence:
The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.
Item b:
The mean is:
Hence, the standard deviation is:
The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.

Answer:
628.32 feet
Step-by-step explanation:
The SkyView Ferris wheel is 200 feet in diameter.
A) The distance around the Ferris wheel would be the Circumference of
the Ferris Wheel.
B) The formula for circumference is given by
circumference = × diameter
C) the distance traveled in one rotation is the length of the circumference
given by circumference = × diameter
∴ circumference = 3.14159 × 200 feet = 628.32 feet.
