Scary statistics about book reading July 13‚ 2006 in General by jc | 1 comment I stumbled on Rich Burridge’s weblog post about book statistics‚ it has some scary numbers : Who is Reading Books (and who is not) One-third of high school graduates never read another book for the rest of their lives. Many do not even graduate from high school. 58% of the US adult population never reads another book after high school. 42% of college graduates never read another book. 80% of US families

As an example of random numbers can be roulette in casino when you never can predict or calculate it. In statistics‚ data often chosen randomly from selected range. In Microsoft Office Excel it can be found by simple function random() or if function randbetween(min number‚max number) which allow select random number from selected range. In this assignment‚

Exercise 01 a) Develop a 99 percent confidence interval for the mean selling price of the home. b) Develop a 95 percent confidence interval for the mean distance of the home is from the center of the city. Exercise 02 a) A recent article in Bangladesh Observer indicated that the mean selling price of the homes in the city of Dhaka is more than Tk. 2200. Can we conclude that the mean selling price in the Gulshan area is more than Tk. 2200? Use the 0.01 significance level

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001.

How to Lie with Statistics Book Summary The book How to Lie with Statistics written by Darrell Huff shows you how statistics are used to mislead; sometimes unintentionally‚ other times on purpose. It gives the readers the knowledge necessary to intelligently question and understand the story behind the numbers. In other words‚ it shows the tricks the crooks use‚ so that honest men can use this knowledge for self defense. I think it’s particularly useful for a manager or an executive to read

1) What is the difference between probability distributions and frequency distributions? Provide an example that demonstrates the difference between the two. A probability distribution directly corresponds to a frequency distribution‚ except that it is based on theory (probability theory)‚ rather than on what is observed in the real world (empirical data). A frequency distribution is based on actual observations. An example would be observing a coin be flipped twenty times. A probability distribution
