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:
Step-by-step explanation:
17.020
Answer:
let's call 8x-6 A and
2xsq - 3x + 5 B
so in the left column the first equations simplifies out to a
the second equation in the left column simplifies out to a
the third equation in the leftcolumn simplifies out to b
in the right column the first equation simplifies out to b
in the second equation right column simplifies out to b
