What is the probability of randomly selecting a z-score greater than z = 0.75 from a normal distribution?
what is the probability of randomly selecting an individual from a normal distribution with a z score less than 0
In a normal distribution, the probability of selecting a score that is greater than the mean is p = 0.50.
For a normal distribution of test scores, what is the probability of randomly selecting a test with a z-score of less than 0.24?
Using the Standard Normal Table. What is the probability a z-score is greater than 0.44? In other words, what is P(z > 0.44)? A. 0.6554 B. 0.3446 C. 0.3300 D. 0.6700
Find the probability that a z-score randomly selected from the normal distribution meets the given condition. The Z-score is between -1.5 and 2.5. In the following problem, check that it is appropriate to use the normal approximation to the binomial. Then use the normal distribution to estimate the requested probabilities More than a decade ago, high levels of lead in the blood put 80% of children at risk. A concerted effort was made to remove lead from the environment. Now,...
