An agricultural field test compares two varieties of corn, silver queen and country gentlemen. The researchers take 10 plots and divide each of these plots in half. Each plot has a similar amount of sun light, shade, quality of soil and irrigation. The variety of corn is randomly chosen for each half of a plot. After the harvest, the yield of corn is measured for each half plot at each location. The yield from silver queen was compared to the yield of country gentlemen. Note: Differences were taken by taking Variety A - Variety B. The 95% confidence interval for the mean is (-0.223, 0.988). What is the correct interpretation of this interval? Group of answer choices There is not enough evidence to say that variety A has a different mean yield then variety B, at 95% confidence. There is convincing evidence that variety A has a higher population mean yield than variety B, at 95% confidence. We have sufficient evidence to show that variety B has a higher population mean yield than variety A, at 95% confidence. There is convincing evidence that population mean yield of variety A is different from variety B, at 95% confidence.
