The data below are yields for two different types of corn seed that were used on adjacent plots of land. Assume that the data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the difference between type 1 and type 2 yields.

Question
The data below are yields for two different types of corn seed that were used on adjacent plots of land. Assume that the data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the difference between type 1 and type 2 yields. What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed? Туре 1 Туре 2 2093 1871 1976 2468 2150 1966 2112 1479 D 2024 1903 2001 2498 2143 1994 2103 1456 In this example, Ha is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the type 1 seed yield minus the type 2 seed yield. The 95% confidence interval is <Ha <: (Round to two decimal places as needed.) What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed? O A. Because the confidence interval only includes positive values and does not include zero, there is not sufficient evidence to support farmer Joe's claim. O B. Because the confidence interval includes zero, there is not sufficient evidence to support farmer Joe's claim. O C. Because the confidence interval includes zero, there is sufficient evidence to support farmer Joe's claim. O D. Because the confidence interval only includes positive values and does not include zero, there is sufficient evidence to support farmer Joe's claim.
