what percent of a standard normal distrubution N(mu=0, sigma=1) is found in each region? draw graph.  |Z| < 0.5

What is the area of a standard normal distribution between z = - 0.83 and z = 1.83?

Scores on the Math Achievement Test form a normal distribution with a mean of μ = 300 and σ = 100. A school distributes scholarships to students who score in the top 10% for this test. What score or higher must be earned to score in the top 10% on the Math Achievement Test?

Find the z-score (to 2 decimal places) such that 8% of the normal curve lies to the right of the z-zone. Also draw a normal curve on your paper and illustrate the z score you found and the region represented.

Find the area of the shaded region under the standard normal curve

Find the area of the shaded region under the standard normal distribution between the given z-scores -1.95 and 1.05.

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.

A recent survey of 1050 U.S. adults selected at random showed that 647 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.
