The given graph represents a population with a Normal distribution. The normal distribution graph shows its peak at x equals 80. The area of the shaded portion of the graph that lies at or above x equals 87 is 0.3085. Which of the statements can we not conclude based on the graph? The proportion of this population that lies at or below ?=87 is 0.3085. The proportion of this population that lies at or above ?=87 is 0.3085. The standard deviation of this population is greater than 7. The proportion of this population that lies at or below ?=87 is 0.6915.
