For this HW you should use Appendix Table for Normal Distribution
Problem 1. Normal Distribution has mean 80 and a standard deviation = 20.
Calculate the z-scores for the following x-values:
a) x = 50
Z = (50-80)/20 = -1.5
b) x = 9
STAT200 Homework for week 3
Problem 1. A fair coin is flipped 7 times.
a) What is the probability of getting exactly 4 heads?
Use Table A-1 for Binomial Distribution.
Probability P(x=4) = .273
Determined by considering possibilities of heads v/s tails (50

8.1 Confidence Intervals for a Population Mean, where is known
A point estimate is a single value (or point) used to estimate an unknown population parameter. To
estimate a population mean we would use the sample mean, x , to be the point estima
Sample Space and Probability
Sample Space consists of all possible outcomes during our statistical experiment.
Probability is calculated as number of outcomes that leads to desirable result over
size of sample space.
Example 1: Flip the coin.
