1.Demonstrate that you understand the basic concepts involving the the normal distribution.In two small paragraphs describe a couple of properties/rules applicable to the normal distribution.

2.Provide an original example of some practical case where we can use the normal distribution (e.g., IQ scores follow a normal distribution of probabilities with a mean IQ of 100 and a standard deviation of 15 IQ points.).Assign your numbers for mean and standard deviation .Make sure is about four times bigger than .Then select any number "a" below or above mean ,but not too far from . The difference (a - ) should be less than 3. Your chosen numbers should be different from those chosen from your fellow classmates.

For example, = 80, = 20, a = 90 (or a = 75).

Find following two probabilities:

1) P(x < a)

2) P(x > a)

Use the formula z = (a - )/ to calculate your z-value.Please refer to the Appendix Table for the Standard Normal Distribution within the eText to find the desired probabilities.

Hint: To find P(x>a) use formula: P(x>a) = 1 - P(x
