Which statement is true of normally distributed data? A.
Approximately 90% of data falls within 2 standard deviations (±2) of the mean.

B.
Approximately 90% of data falls within 3 standard deviations of (±3) the mean.

C.
Approximately 95% of data falls within 2 standard deviations (±2) of the mean.

D.
Approximately 95% of data falls within 3 standard deviations (±3) of the mean.

C

Approximately 95% of data falls within 2 standard deviations (±2) of the mean.

Explanation

According to the empirical rule of normal distribution:

Approximately 68% of the data falls within ±1 standard deviation of the mean

2. Approximately 95% of the data falls within ±2 standard deviations of the mean

3. Approximately 99.7% of the data falls within ±3 standard deviations of the mean.

Therefore, among the given options, only option C adheres to the empirical rule of the normal distribution. Therefore, the option C is correct

60%

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
