Today, 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
Use graph paper for your graphs. For Section 6.2, we used the TI83/84 calculator function (see http://stats.jjw3.com/math1431/ti83binProb.htm) to calculate the binomial probabilities. 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, we will cover a few more examples of binomial probabilities. Also, 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.
