Answer:
s ≈ 105
Step-by-step explanation:
<u>Given:</u>
- The data set: 700, 735, 680, 890, 755, 740, 670, 785, 805, 1050, 820, 750
<u>To find:</u>
- The standard deviation of the data
<u>Steps:</u>
To find the standard deviation, first write the computational formula for the standard deviation of the sample.
Take the square root of the answer found in step 7 above. This number is the standard deviation of the sample. It is symbolized by . Here, we round the standard deviation to the nearest whole number.
Rounding to the nearest whole number:
s ≈ 105
