Answer:
Mean = 272.3
sd = 37.7
Step-by-step explanation:
Mean = sum/n
(221+248+251+255+259+263+264+272+291+297+374) ÷ 11
= 2995/11
= 272.2727273
Variance = (sum of x²)/n - mean²
[(221²+248²+251²+255²+259²+263²+264²+272²+291²+297²+374²)/11] - (2740/11)²
= (831067/11) - (2995/11)²
= 1419.107438
sd² = variance
sd = sqrt(1419.107438)
sd = 37.67104243
The diameter is 18 so in exact terms the circumference would be 18 pi but if you were to get an estimate of the circumference you would multiply the diameter, 18, by 3.14 and get an answer of 56.52. So the circumference in exact terms is 18 pi or estimated to be 56.52 in.

Answer:
0.2
Step-by-step explanation:
A probability is from 0 (will definitely not happen) to 1 (will definitely happen).
The closer to 0, the more unlikely it is that it will happen.
Answer: 0.2
