Question

The following data represent quantities of tea leaf pluckings (tender shoots from tea plants) from sixteen different plots of tea bushes intended for experimental use in Ceylon, a type of tea from Sri Lanka. The tea bushes are randomly divided into four different treatment groups. Experimenters wish to determine if the mean number of pluckings differs among the four treatments. Test this using 5% significance, assuming that these samples are drawn from normal populations with equal variances. Treatment 1 Pluckings 88, 94, 109, 88 , Treatment 2 Pluckings, 102, 110, 105, 102 Treatment 3 Pluckings, 91, 109, 115, 91 Treatment 4 Pluckings 88, 118, 94, 96.
