1) in the normal distribution for z-scores, a z-scores of _______ is less than exactly 40% of all other z-scores. 2) in order for the distribution of the sample mean to be Normal, a population size of ___ or more is required if the sample size is 36.
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
a) If you select a random z-score from the normal distribution, what is the probability that you will get a value greater than -2.5? Put differently, P(z>1.5) = ?
