For a standard normal random variable, what z-score has (a) probability 0.175 to the right? (3 decimal places) (b) probability 0.950 to the left? (3 decimal places)
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,...

Determine the z-score that would represent the probability of an event with an 80% likelihood of happening. (You must draw a graph first. Then round your answer to 2 decimal places.)
QUESTION 27 Using the Standard Normal Table. What is the probability a z-score is between -1.11 and 0.91? In other words, what is P( -1.11 < z < 0.91)? A. 0.6851 B. 0.5186 C. 0.9521 D. 0.0479 QUESTION 28 Consider this question: For a certain set of data, what percentage of individuals would have a z-score less than 1.45? (Hint: this is asking what percentage of the normal curve would fall less than that z-score.) (Hint: think about where this...
A study of long-distance phone calls made from General Electric Corporate Headquarters in Fairfield, Connecticut, revealed the length of the calls, in minutes, follows the normal probability distribution. The mean length of time per call was 4.00 minutes and the standard deviation was 0.40 minutes. a. What fraction of the calls last between 4.00 and 4.60 minutes? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.) Fraction of calls b. What fraction of the...
(Normal distribution: Finding a raw score) Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 19. What is the minimum score needed to be in the top 10% of the scores on the test? Carry your intermediate computations to at least four decimal places, and round your answer to one decimal place.
