Preliminary data analyses indicate that the assumptions for using pooled t-procedures are satisfied. Independent random samples of 103 plots with cropland and 99 plots with grassland yielded the given summary statistics for the number of species of bird. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean number of species in the two regions? Cropland Grassland x overbar 1 equals 14.12 x overbar 2 equals 15.87 s 1 equals...
