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%
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 a z-score greater than z = -0. 75 from a normal distribution?
A normal distribution of scores in population has a mean of µ = 100 with σ = 20. A. What is the probability of randomly selecting a score greater than X = 110 from this population? B. If a sample of n = 25 scores is randomly selected from this population, what is the probability that the sample mean will be greater than M = 110?

1. Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of 0 and a standard deviation of 1. Find the probability that a given score is less than 3.87 and draw a sketch of the region. 2. Assume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw...
In a normal distribution, the probability of selecting a score that is greater than the mean is p = 0.50.
In a standard normal distribution, find the following values: The probability that a given z score is less than -2.67 The probability that a given z score is between 1.55 and 2.44 The z scores that separates the most inner (middle) 82% of the distribution to the rest The z score that separate the lower 65 % to the rest of the distribution
