In the last two class periods we covered Section 6.1 (Discrete Random Variables) and Section 6.2 (Binomial Probability Distribution).
The next homework assignment is due on Monday, 19 October 2009 and consists of the following:
Section 6.1: # 1, 3, 7, 8, 11, 16, 17, 19abcfg, 21abcef, 23abc, 25abc, 27, 28, 30
Section 6.2: # 1-27 odd, 29, 30, 35, 37, 39, 43, 45, 47, 49
Use graph paper for your graphs. You may use the calculator functions (see http://stats.jjw3.com/math1431/ti83binProb.htm) to calculate the binomial probabilities for the homework. Keep in mind what I expect for your work when calculating binomial probabilities, for example: binompdf(12,0.4,3)=0.142.
The next quiz is on Monday, 19 October 2009 and will cover finding binomial probabilities.
On Monday and Wednesday of next week, we will discuss most of Chapter 7 – recall that we already talked about most of these ideas in a previous section. We will use the following TI83/84 instructions:
How to find area under the normal curve: http://stats.jjw3.com/math1431/ti83norm.htm
How to find and graph the area under a normal curve: http://stats.jjw3.com/math1431/ti83normArea.htm
How to find a z-score given the area under a normal curve: http://stats.jjw3.com/math1431/ti83invNorm.htm
How to check if data is normally-distributed: http://stats.jjw3.com/math1431/ti83normHist.htm
If you have any questions regarding the homework before Monday, please stop by my office or email me – you can email me over the weekend.
