Three different checkpoints in a water distribution system are tested for bacterialcontamination. Several randomly selected water samples from each location are usedto produce bacterial contamination scores on a scale from 1 and 20. Is the level ofcontamination the same everywhere?Location 1Location 2Location 313141151561198Sum 483230The null hypothesis is that the bacterial contamination is the same at all threelocations. Your research hypothesis is that at least one location has a different meancontamination score.You calculate that Ex = 110 and Ex? = 1200. Perform the rest of the ANOVAcalculations to determine the Within Groups degrees of freedom.86372. It is claimed that the mean household size in the River Terrace neighbourhood is 3.5persons.

||| Interpreting relative frequency histograms The Moon Illusion refers, roughly speaking, to the common experience that the moon appears larger (and closer to us) when it is near the horizon than when it is at its zenith. To investigate, we have designed an experiment in which participants must adjust the diameter of a variable circular light placed at eye level to match the diameter of a fixed circular light placed well above eye level. (See, for example, Kaufman, L. & Rock, I. (1989), "The moon illusion thirty years later," chapter 8 in M. Hershenson (Ed.) The Moon Illusion, Hillsdale, NJ: L. Earlbaum.) We have tested 25 participants and recorded for each participant her experimental "adjustable/ fixed ratio." Our data are summarized in the following histogram. Frequency 6+ + 2- 0 0 0.2 7 8 0.4 0.6 Adjustable/ fixed ratio 4 X 0.8 5 2 Based on the histogram, find the proportion of adjustable/ fixed ratios in the sample that are greater than or equal to 0.80.

Mr. Palmer, has been teaching beginners how to fix their stroke for the last 10 years. The mean golfing score for all past students who learned with Mr. Palmer is 79. This golfing cycle, he tried a new teaching method using simulations instead of real-world golf. He then had 15 of his students that used his new method take a golfing test. Enter the data into SPSS. Use this dataset to answer this question: did Mr. Palmer’s students perform better on the golfing test using the new method as compared to the traditional teaching technique? 1. From the output, report the test statistic and the probability (obtained p-value, called “sig” in the output). Remember to include degrees of freedom when you report t-values. 2. Will you reject or fail to reject the null based on the SPSS output (Remember to use numbers from the output only to make your statistical conclusion. If you use a critical t, you will get no points.).
