Compare the two separate scatterplots. In particular, how do the associtation compare between women with pets vs. women without pets? Does one group have more variation in systolic blood pressure than the other? If so, for which group? Does systolic blood pressure seem higher for common ages between the two groups? If so, for which group?
This question is about Experimental design.
An important issue in conservation biology is how dispersal among populations influences the
persistence of species in a fragmented landscape. Molofsky and Ferdy (2005) measured this in the
annual plant, Cardamine pensylvanica, a weed that produces explosively dispersed seeds. Four
treatments were used to manipulate seed dispersal by changing the distance among experimental
plant populations. These treatments were adjacent (continuous treatment), separated by 23.2 cm
(medium), separated by 49.5 cm (long), or separated by partitions that blocked all seed dispersal
among populations (isolated). Treatments were randomly assigned to plant populations. The data
shown are the number of generations that the populations persisted in six replicates of each
treatment. Test whether the persistence of species differ with distance among experimental plant
populations at 5% significance level. Conduct a follow up analysis when necessary.

Chi-Square Good of Fit Problem: Automobile insurance is much more expensive for teenage drivers than for older drivers. To justify this cost difference, insurance companies claim that the younger drivers are much more likely to be involved in costly accidents. To test this claim, a researcher obtained information about registered drivers from the Department of Motor Vehicles (DMV) and selected a sample of n = 300 accidents reports from the police department. The DMV reports the percentage of registered drivers in each age category as follows: 16% are younger than age 20,; 28%are 20 to 29 years old;and 56% are age 30 and older. The number of accidents reports for each age group is as follows: Under age 20 Age 20-29 Age 30 and older 68 92 140 Is…arrow_forwardA researcher, after performing cost analysis finds that the greater expenditure incurred by using organic farming techniques including organic pesticides is justified if it yields an average of at least 50 kg more soybean per hectare than the yield using regular farming technique using chemicals. In a pilot study, the performances of plots with soybean using organic and inorganic farming techniques are examined, with data as follows. Do these data provide sufficient evidence to indicate that fields with organic farming yield more to justify extra cost?

- A survey of high school students was done to examine whether students had ever driven a car after consuming a substantial amount of alcohol (1=yes, 0=no). Data was collected on their sex (male/female), race (White/non-White), and grade level (9,10,11,12). Researchers realized that the impact of race on consuming alcohol before driving might vary by grade level and decided to fit the following model. Variable Coding = 1 if Intercept Sex () Female Race () Black Grade level ( 9th grade 10th grade 11th grade [Reference = 12th grade] Attached is the logistic model 1.
