-] 0 determine how climate change and habitat loss will inuence Antarctic species, baseline estimates of population sizes and 'stributions are needed. To this end, a group of researchers estimated the population sizes of all breeding colonies of emperor penguins (Aptenodytesfosteri) along Antarctic coastlines using satellite imagery (Fretwell et a1., 2012). For each E breeding colony encountered, the researchers detemiined the latitude, longitude, and area (m2) of the colony, and estimated g the total number of emperor published estimates. 8' Han Learning penguins present. Then, they compared their colony size estimates to previously Suppose the researchers want to determine if there is a linear relationship between the colony areas and the previous population estimates, so they decide to conduct a two-tailed t-test for no linear relationship. From 29 data points, they calculate the linear regression equation to be 5; : 1813.11531 + 0.80065x where 3: is the predicted previous population estimate and x is the colony area. The standard error of the slope, SE5, is 0.12337. The researchers examine the residuals plot and determine that all of the requirements for using a t-test for no linear relationship have been met. First, determine the null and alternative hypotheses of the test. [3 represents the slope of the population regression line and p represents the population correlation coeicient. Select the null and alternative hypotheses from the list
