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

A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1482 and the standard deviation was 315. The test scores of four students selected at random are 1910, 1200, 2210, and 1390. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1910 is (Round to two decimal places as needed.)

For the population of one town, the number of siblings, x, is a random variable whose relative frequency histogram has a reverse J-shape. The mean number of siblings is 1.3 and the standard deviation is 1.5. Let x denote the mean number of siblings for a random sample of size 32. Determine whether the distribution of x is normal or approximately normal and find its mean and standard deviation.
