The director of an obesity clinic in a large northwestern city believes that drinking soft drinks contribute to obesity in children. To determine whether a relationship exists between these two variables, she conducts the following pilot study. Eight- 12-year-old male volunteers are randomly selected from children attending a local junior high school. Parents of the children are asked to monitor the number of soft drinks consumed by their child over a one week period. The children are weighed at the end of the week and their weights converted into body mass index (BMI) values. The BMI is a common index used to measure obesity and takes into account both height and weight. An individual is considered obese if they have a BMI value  30. The following data or collected: child.          # of soft drinks consumed      BMI 1                            3                                        20 2                            1                                         18 3…
A pharmaceutical company has developed a drug that is expected to reduce hunger.  To test the drug, three samples of rats are selected with n=9 in each sample.The first sample receives the drug every day.  The second sample is given the drug once a week, and the third sample receives no drug at all (the control group).  These assignments of drugs are called treatments.The (dependent) variable being compared is the amount of food eaten by each rat over a 1-month period.  These data are analyzed by an ANOVA, and the results are reported in the following summary table.  How many groups (or population means or treatments) are being compared in this problem? _________ (Enter a whole number) What is the total number of data used in this problem?  _________(Enter a whole number) Fill in all missing values in the table.  (Hint:  Start with the df column and your above answers.)If there are decimal places in your answer, provide 2 or more decimal places.

Peter Boag, studied the inheritance of beak depth in Galapagos finches by looking at the relationship between parent beak depth (in mm) and that of their offspring.  He collected two sets of parent offspring data, once in 1976 and again in 1978.  For both years he followed birds to determine which pairs belonged to which nests. Most of the parents had been previously captured so their beak depths were known.  He then captured the offspring when they fledged and measured their beak depth.  He calculated the "midparent" beak depth (the average beak depth of the two parents) and then compared that to beak depth of their offspring.   Use regression analysis to estimate heritability for the trait beak depth from the Galapagos finches data in the above table.
