Select one answer 10 points Rainfall and corn crop yield

Select one answer 10 points Rainfall and corn crop yield reported for the 38 years from 1890 through 1927 give us the scatterplot shown below with an r 0 0426 Yield is the number of ears of corn measured in metric tons per hectare rainfall is in inches 25 20 B O 15 D O 5 9 11 Crop Yield 13 Rain Based on corn crop yield from Ezekiel M and K A Fox 1959 Methods of Correlation and Regression Analysis Wiley New York 15 The plot shows a positive linear relationship between the inches of rainfall and the size of the corn yield Based on the scatterplot and the value of the correlation coefficient it would make sense to test the significance of this observed linear relationship between crop yield and rainfall Which of the following are the appropriate null and alternative hypotheses A O H Crop yield is related to rainfall H Crop yield is not related to rainfall H Crop yield is not related to rainfall H Crop yield is related to rainfall 17 19 H Crop yield is not linearly related to rainfall H Crop yield is linearly related to rainfall H Crop yield is linearly related to rainfall H Crop yield is not linearly related to rainfall
