Answer:
{x ∈ ℝ | x ≠ 2}
Step-by-step explanation:
Using the Empirical Rule, it is found that the standard deviation of the sample is of:
C. 4
By the <em>Empirical Rule</em>, 95% of the measures are within 2 standard deviations of the mean, that is, between 2 standard deviations below the mean and 2 standard deviations above the mean.
95% of people's heights are <u>between 168 and 184 centimeters</u>, hence, there are 4 standard deviations between 168 and 184 centimeters. Then:
Hence, option C is correct.
