The question was: If the distribution was normal, between which two values would 68% of the values lie?
Your Answer: [0, 1]
Answer and explanation: Your answer is incorrect.
In a normal distribution, 68%
of the observations fall within one standard deviation of the mean. The
mean is 110.23 and the standard deviation is 23.63. To find the lower limit,
calculate:
110.23 - 23.63 = 86.6. Similarly, the upper limit is 110.23 + 23.63 = 133.86.
Rounding off, the range is from 87 to 134.
