Across 8. The mean µ and standard deviation σ completely specify the Normal distribution N(μ, σ). 9. z = (x − µ)/σ how many standard deviations x lies from the distribution mean

Down 1. N(0, 1). normal random variable has a mean of zero and a standard deviation of one 2. probability that a randomly selected score < than or equal to a specified value 3. Described by bell-shaped, symmetric, unimodal density curves 4. A way to judge the adequacy of a Normal model. 5. Width of one, two and three standard deviations 6. Overall pattern of a distribution 7. x, subtract the mean of the distribution and then divide by the standard deviation
