Given
n = 196 μ = 55 St.Dev = 42 μ X = 58
Find the Standard Error
S E = σ n = 42 196 = 3
Find the z-score
z = 55 58 3 = 0.75

When using the cumulative normal distribution table, the area under the curve given is the area to the _____ of that particular z-score.
One method of finding the area to the right of a particular z-score, is to use the following: 1 - area to the _____
To find the area _____ two z-scores, we look up the area to the _____ of each value and subtract the smaller area from the larger area.
To find the area _____ of two z-scores, we add together the area to the _____ of the smaller z-score with the area to the _____ of the larger z-score.

Describe exactly what information is provided by a z-score. A positively skewed distribution has μ = 80 , σ = 12. If this entire distribution is transformed into z-scores, describe the shape, mean, and standard deviation for the resulting distribution of z-scores.

I am looking at Central Limit Theorem. It says that for a series of random sample W 1 , , W 2 under the same mean μ and standard deviation σ, then the random variable
W ¯ μ σ / n
follows normal distribution. However, it seems like for Binomial samples,
W ¯ μ σ = W ¯ n p n p ( 1 p )
is normal. I want to know where the n−−√ term in the denominator went?

 In hypothesis testing, we have scenarios that have both dependent and 
independent samples. Give an example of an experiment with (1) 
dependent samples and (2) independent samples.
