3.) You will be finding probabilities using excel. Use the Excel instructions for Binomial Distribution (=BINOMDIST(x, n, p, true or false)) and/or Excel Instructions under Excel Examples folder to evaluate the following problems. State which probabilities are unusual.

a.) P(X 8), n = 20, p = .8 b.) P(X > 6), n = 10, p =.15

c.) P(X < 14), n = 40, p = .35

4.) Construct a binomial distribution (table) using Excel functions for the following: Twelve percent of people in the US eligible to donate blood do. You randomly section 15 eligible blood donors and ask them if they donate blood. Create the histogram of this probability distribution. Describe the histogram.

5.) Use Excel functions to find the following probability of Z-distribution

a.) P(Z < -1.74) b.) P(Z > .58)

c.) P(-1.4 < Z < 2.1)

6.) Use Excel functions to find the following probability of Normal distribution

a.) P (X > 70) when X ~ N (65, 10)

b.) P(20 < X < 40) when X ~ N (32, 12)

7.) Use Excel functions to find the X value(s) given the probability when X ~ N(45, 5)

a.) P18 b.) Q3
