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? Type 1 2060 1932 2009 2516
2122 2076 2255 1434 Type 2 2006 1942 2008 2442 2103 1986 216 1448
In this​ example, mu Subscript dμd is the mean value of the
differences d fo 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
nothingless than
