Assume we have data demonstrating a strong linear link between the amount of fertilizer applied to certain plants and their yield. Which is the independent variable in this research question?
Algal blooms can have negative effects on an ecosystem by dominating its phytoplankton communities. Gonyostomum semen is a nuisance alga infesting many parts of northern Europe. Could the overall biomass of G. semen be controlled by grazing zooplankton species? A research team examined the relationship between the net growth rate of G. semen and the number of Daphnia magna grazers introduced in test tubes. Net growth rate was computed by comparing the initial and final abundance of G. semen in the experiment, with a negative value indicative of a decrease in abundance. The study also examined the grazing effect of another species, Daphnia pulex, on the abundance of the nuisance alga G. semen in the lab. The table displays the findings

To study this, a researcher examined a species of coral that is found in the Caribbean Sea and the Gulf of Mexico. At 12 localities, he determined the average annual calcification rate of coral over a period of several years and the average annual maximum sea surface temperature during the same period. Calcification rate affects the growth of coral, with higher rates corresponding to greater growth. The table contains data for these 12 localities.

- A botanist found a correlation between the length of an aspen leaf and its surface area to be 0.94. Why does thecorrelation value of 0.94 not necessarily indicate that a linear model is the most appropriate model for therelationship between length of an aspen leaf and its surface area? (A) The value must be exactly 1 or to indicate a linear model is the most appropriate model. (B) The value must be 0 to indicate a linear model is the most appropriate model. (C) A causal relationship should be established first before determining the most appropriate model. (D) The value of 0.94 implies that only 88% of the data have a linear relationship. (E) Even with a correlation value of 0.94, it is possible that the relationship could still be better represented by a nonlinear model.arrow_forwardTo predict the market share of one of their products, a manufacturer of consumer electronics products hired a market research company to conduct a study that relates market share in a particular geographic region (in %) to the average annual household income and the number of retail outlets per 100,000 residents. The results of a multiple regression model to predict market share from Household income (in thousands of dollars) and number of outlets per 100,000 residents are given below. a) How much of the variation in market share can this model predict? Is this statistically significant? b) Someone claims that each additional outlet will increase the market share by more than 1.5%, regardless of what the household income is. Perform the appropriate hypothesis test to check this claim with a 5% significance level. c) What increase in market share would your model predict for every two additional retail outlets in a region where the annual household income is $75,000?
