Question 10 6 pts In a normal distribution, what is the approximate probability (as a percentage) of randomly selecting a value with a z-score less than z = +1.65? In other words, what percentage of scores fall below az score of 2.5% 95.0% 5.0% 97.5%
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,...
In a normal distribution, the probability of selecting a score that is greater than the mean is p = 0.50.

A manufacturing process makes rods that vary slightly in length but follow a normal distribution with mean length 25 cm and standard deviation 2.60. What is the probability of randomly selecting a rod that is shorter than 22 cm? P(X<22)=P(Z< ) = Round your z-score and probability to four decimal places.
