Consider the normal distribution curve. A graph shows the horizontal axis numbered 50 to 78. There is no vertical axis. Variance = 7. A line shows an upward trend from below 50 to 64 and a downward trend from 64 to Over 78. The space beyond 78 is labeled x. Which statements are true about the curve? Check all that apply. The standard deviation of the data is 64. The variance of the data is 49. The median is 64. The data point 75 is less than one standard deviation from the mean. The data point 50 is two standard deviations away from the mean.
