19. You might think that increasing the resourcesavailable would elevate the number of plant spe-cies that an area could support, but the evidencesuggests otherwise. The data in the accompany-ing table are from the Park Grass Experiment atRothamsted Experimental Station in the U.K.,where grassland field plots have been fertilizedannually for the past 150 years (collated byHarpole and Tilman 2007). The number of plantspecies recorded in 10 plots is given in responseto the number of different nutrient types addedPlot12345678910Number ofnutrients added0003144 E23Number ofplant species36363234333020232116 a. Draw a scatter plot of these data. Whichvariable should be the explanatory variable(X), and which should be the responsevariable (Y)?b. What is the rate of change in the numberof plant species supported per nutrient typeadded? Provide a standard error for yourestimate.c. Add the least-squares regression line to yourscatter plot. What fraction of the variation inthe number of plant species is "explained" bthe number of nutrients added?d. Test the null hypothesis of no treatmenteffect on the number of plant species.

B. What is the equation of the regression line for the set of 9 points? y=___ C. Choose the correct description of the results below. The removal of the point has a significant impact on the regression line. There is no regression line for the second case because the data are in a pattern. The regression line is very similar in both cases. The regression line changes, but the change is small.
Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the plant- ing of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).2.1 2.2 1.7 1.6 2.3 3.1 1.5 2.6 2.4 2.2 With a .05 level of significance, test to see whether the mean tree-planting time differs from two hours. a.

The data in Table 7..7 are collected in an experiment designed to investigate the impact of different positions of the mother during ultrasound on fetal heart rate. Fetal heart rate is measured by ultrasound in beats per minute. The study includes 20 women who are each assigned to one position and have the fetal heart rate measured in that position. Each woman is between 28 weeks, and 32 weeks, gestation. Is there a significant difference in mean fetal heart rates by position? Run the test at a 5% level of significance.
