Problem 37

Dowsing Before drilling for water, many rural homeowners hire a dowser (a person who claims to be able to sense the presence of underground water using a forked stick). Suppose we wish to set up an experiment to test one dowsers ability. We get 20 identical containers, fill some with water, and ask him to tell which ones they are. a) How will we randomize this procedure? b) The dowser correctly identifies the contents of 12 out of 20 containers. Do you think this level of success is statistically significant? Explain. c) How many correct identifications (out of 20) would the dowser have to make to convince you that the forked-stick trick works? Explain

STAT-5615: Statistics in Research I Lecture 11 ANOVA Ott & Longnecker Ch 8 Dr. Christian Lucero Virginia Tech Fall 2016 ANOVA - Analysis of Variance Despite it’s name, the Analysis of Variance is a very useful method that can be used for many di▯erent statistical analyses. The most important way that we will use it is to compare the means of many independent samples simultaneously. Main Ideas Suppose we have multiple populations that we want to compare a possible null is H 0 m 1 = m 2= ▯▯▯ = mt where t is the total number of population groups. The alternative is that at least one mean di▯ers, i.e. H A m m 6= mn for some m
